Muscular System
The muscular system allows the body to move through muscle contraction and relaxation. There are approximately 600 muscles in the human body. Muscles are categorized as voluntary or involuntary. Voluntary muscles like those in the arms and legs can be consciously controlled, while involuntary muscles in organs cannot. The three main types of muscle are skeletal, smooth, and cardiac. Skeletal muscles move bones and are striated and voluntary. Smooth muscles are found in organs and are involuntary. Cardiac muscle is only located in the heart and is also involuntary. Muscles work in opposing pairs to enable movement, such as the biceps and triceps raising and lowering the arm.
Muscles
There are 660 muscles in the human body that are formed from muscle cells and make up the muscular system. Muscles contract and relax alternately to enable movement as animals move from one place to another. Voluntary muscles, also known as skeletal muscles, allow for voluntary movement by working with bones like the muscles in the hands and legs. Involuntary muscles are not connected to bones and are found in tubular organs to enable involuntary movements, such as the muscles in the stomach and urinary bladder.
Muscular system
The muscular system allows for movement of the body and gives it form and shape. It is made up of many muscles that have specific functions like lifting, pulling, and rotating. The muscular system interacts with other body systems like respiratory and nervous. Common illnesses of muscles include muscular dystrophy and chronic fatigue syndrome. There are over 600 muscles in the body with the largest being the gluteus maximus.
Major skeletal muscles in the body
Skeletal muscles are voluntary muscles that are attached to bones and allow for movement of the body. There are several groups of skeletal muscles that control movement in the legs, arms, trunk, neck, and face. The functions of skeletal muscles include force production for locomotion, maintaining posture, stabilizing joints, and generating heat. Some major skeletal muscles are the gluteus maximus and quadriceps in the legs, the deltoids and biceps in the arms, the abdominal and back muscles in the trunk, and the facial muscles that control expression.

Bones provide structure and protection for organs, while joints connect two or more bones and muscles contract to pull on bones via tendons. The document provides tips for caring for the locomotor system such as warming up before exercise, stretching after, getting enough sleep, eating calcium-rich foods, and avoiding bad posture or heavy lifting.
Locomotor system
The document discusses the key components of the human locomotor system. It includes bones that make up the skeleton, which comes in three parts and provides structure and protection. There are three types of bones - long, short, and flat. Joints connect the bones and also come in three types - flexible, semi-flexible, and fixed. Muscles are connected to bones and contract or relax to move the skeleton, with two types - voluntary and involuntary. Together, bones, joints, and muscles allow the human body to move.
The motor system
The document summarizes the key components and functions of the human motor system. It discusses that the skeletal system provides support, protection, movement, storage, and production of blood cells. The skeletal system consists of bones, cartilage, and joints. Bones are made of living tissue and minerals. Joints connect bones and allow movement, with examples being ball-and-socket and hinge joints. Muscles work with bones to enable movement. The nervous system controls voluntary and involuntary muscle movement.
Muscular system skeletal
Skeletal muscles are made up of bundles of fibers that are attached to bones via tendons. They produce movement by contracting and pulling the tendons, which moves the bones. The origin is the stationary bone attachment, the insertion is the moving bone attachment, and contraction pulls the insertion toward the origin to cause movement.
My Muscular System Powerpoint
The document discusses the human muscular system, including that muscles move the body like strings move a puppet, there are about 650 muscles in the human body making up half of the body weight, and muscles are important for holding organs in place, moving bones, chewing food, and various other functions like running, playing, and smiling. It also notes that frowning uses more muscles than smiling and provides tips for keeping muscles strong through diet and exercise.

Skeletal system 6
The musculoskeletal system includes bones, muscles, and joints. It is composed of 206 bones that support the body, protect organs, and allow for movement through connection to muscles. There are over 600 muscles made of muscle cells that contract and relax, attaching to bones via tendons to enable body part movement. Joints include fixed, semi-movable, and movable types that connect bones and facilitate different ranges of motion.
The Locomotor System
The locomotor system is made up of the skeleton and musculature and is responsible for movement. The skeleton provides structure, protection, and attachment points for muscles. Muscles are attached to bones via tendons and allow both voluntary and involuntary movement when signaled by the nervous system or other organs. Bones and muscles are classified based on their location in the head, trunk, or limbs. Joints connect bones and allow different ranges of motion. Tendons are flexible but non-elastic fibers that connect muscles to bones.
Muscles
There are three main types of muscles in the human body:
1. Smooth muscles are involuntary and found in the digestive system to help move food.
2. Cardiac muscles are involuntary and found only in the heart to pump blood through the circulatory system.
3. Skeletal muscles are voluntary and attached to bones by tendons, allowing for movement of the body. They work in pairs to flex and extend joints.
Muscular system
The muscular system allows the body to move through the contraction and relaxation of muscles. There are over 600 muscles in the human body that work with the skeletal system. Muscles are categorized into three types - skeletal, smooth, and cardiac muscles - with skeletal muscles being voluntary and responsible for movement of the bones, while smooth and cardiac muscles are involuntary. Muscles contract when one muscle contracts while its opposing muscle relaxes, allowing movement, and muscles require energy to contract before needing rest.

Type, structure and functions of muscle
Origin, Insertion, and action of muscles
Muscle:
Muscle is a soft tissue and it is one of the 4 basic tissues, along with nervous tissue, epithelium, and connective tissue.
Muscles helps in movement, support and protection of internal organs.
Muscle cells or myocytes contain protein filaments called myofilaments actin & myosin that producing a contraction that changes both the length and the shape of the cell.
Types of Muscles:
There are 3 types of muscles: skeletal, cardiac & smooth muscle
Skeletal muscle or “voluntary muscle” or striated Muscles is attached to bone, helps in movement & in maintaining posture.
Smooth muscle or “involuntary muscle” or non striated muscles is found within the walls of organs and structures
Cardiac muscle is also an "involuntary muscle" found only in the heart.
Structure of Skeletal muscle:
Skeletal muscle consist plasma membrane is called sarcolemma, the cytoplasm is called sarcoplasm & specialized sarcoplasmic reticulum that play important role in regulation of Calcium.
Cells contain many nucleus peripherally
It consist of number of elongated cells called muscle fibers or muscle cell , that consist of myofibrils (elongated protein molecules).
These Muscle fibers are arranged in bundle called fasciculi
Each muscle fibers covered by endomysium, each fasciculi covered by perimysium & the whole muscle is covered by epimysium.
Neuromuscular junction (NMJ) or myoneural junction is a chemical synapse between a motor neuron and a muscle fiber.
It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction.
Properties of skeletal muscle:
Excitability: this refers to muscle tissue being able to react to nervous stimulation.
Extensibility: this refers to the ability of muscle tissue to lengthen when contracting
Elasticity: this refers to the ability of muscle tissue to return to its normal resting length once it has been stretched.
Contractility: this refers to the capacity of a muscle to contract or shorten forcibly when stimulated by nerves and hormones
Muscle contraction:
Muscle use the movement of actin against myosin to create contraction.
In skeletal muscle, contraction is stimulated by electrical impulses transmitted by the nerves
Cardiac and smooth muscle contractions are stimulated by internal pacemaker cells which regularly contract, and propagate contractions to other muscle cells they are in contact with.
All skeletal muscle and many smooth muscle contractions are facilitated by the neurotransmitter acetylcholine.
Types of muscle contraction:
Isotonic contractions maintain constant force or tone in the muscle as the muscle length changes
Isometric contractions changes in force without changing the length of the muscle
Muscle tone is defined as the tension in a muscle at rest.
Function of skeletal muscles
Body movement (Locomotion)
Maintenance of posture
Respiration
Constriction of organs and vess

introduction to muscular system
The muscular system is responsible for movement of the body and is composed of three muscle types: skeletal, cardiac, and smooth muscles. Skeletal muscles are voluntary muscles that attach to bones and allow for locomotion. Cardiac muscle is exclusively located in the heart and pumps blood involuntarily. Smooth muscles line organs and blood vessels and function involuntarily to aid processes like digestion and blood flow.

Breezes
The document discusses various atmospheric phenomena such as air temperature, pressure, and heating. It explains how thermometers are used to measure air temperature and how air is heated by the sun, conduction, and convection. It also discusses specific heat and how cement gets hotter than soil. Additionally, it summarizes sea and land breezes caused by uneven heating of land and sea. Other topics covered include monsoons, trade winds, the Intertropical Convergence Zone (ITCZ), ozone formation and depletion, and the greenhouse effect.
Responsible parenthood
The document discusses the Responsible Parenthood and Reproductive Health Act of 2012 in the Philippines, which guarantees universal access to contraception, fertility control, sex education, and maternal care. It mandates the government to promote all effective and legal family planning methods. The bill also requires reproductive health education in schools and guarantees reproductive healthcare for female employees. It aims to promote responsible parenthood through a multi-dimensional approach integrated into anti-poverty programs.
The atmosphere
The document discusses the layers of Earth's atmosphere. It is divided into five main layers from lowest to highest:
1) The troposphere, extending up to 9-16 km, contains weather patterns and decreases in temperature with altitude.
2) The stratosphere, up to 50 km high, contains the ozone layer and has a temperature that initially increases with altitude.
3) The mesosphere, up to 85 km high, has a sudden temperature increase then decrease with altitude and contains ionized layers.
4) The thermosphere, 80-640 km high, has extremely high temperatures over 1000°C and contains the ionosphere responsible for reflecting radio waves.
5) The exosphere, over
Gravity
The document discusses the force of gravity and its effects. It explains that gravity is a downward pulling force that attracts all objects on Earth toward its center. It causes things thrown up to fall back down, and makes downward movement faster than upward movement. Gravity is responsible for many phenomena we observe, such as leaves falling from trees, objects slipping from our hands, and kites falling when the wind stops blowing. It establishes our weight and keeps us and everything on Earth from floating off into space.
Maternal health concerns
This document discusses maternal health concerns before, during, and after pregnancy. Before pregnancy, women should see their doctor to discuss any existing health problems and how treatment may need to be adjusted. During pregnancy, women may experience a range of symptoms from mild discomforts to severe illnesses. Common health conditions experienced during pregnancy include anemia, UTIs, gestational diabetes, and hypertension. After pregnancy, women can experience postpartum depression caused by hormonal changes after childbirth. Proper prenatal and postnatal care is important for both mother and baby's health.
Energy
Most activities involve energy in different forms. Sound, light, heat, and chemical/mechanical energies are used from waking up until moving around. Forces like gravity, wind, water, electricity, and magnetism can push or pull objects to cause motion. Motion is the change in position of an object due to force. Forces can make objects move, change their speed and direction of movement, stretch or compress, or cause up and down motion through balanced or unbalanced opposing forces.
Heat energy
The document discusses heat energy and its effects on the human body. It explains that exposure to the sun's heat energy can cause sweating, thirst, reddening of the skin, and smelling musky. It then provides tips for protecting against excessive heat, such as avoiding direct sun exposure especially from 10am-2pm, drinking plenty of water, wearing loose cotton clothes, and staying alert for signs of heat illness like dizziness or fainting.
Friction
Forces can cause objects at rest to move or change an object's motion. There are two main types of forces - contact forces that require touching and non-contact forces like gravity. Friction is a contact force that resists the movement of objects in contact with each other. The document discusses the different types of friction like static, sliding, and rolling friction and how friction affects motion. It also describes ways to reduce friction using lubricants and wheels and ways to increase friction using rough surfaces. Safety measures around friction to prevent accidents are mentioned.
Dating, courtship, and marriage
This document discusses the topics of dating, courtship, and marriage. It defines infatuation and love, and notes that dating is a form of courtship where couples engage in social activities together. There are different types of dates like standard, double, and group dates. Dating is important as it allows couples to develop affection, strengthen their relationship, get to know each other's character, and have fun. Courtship precedes engagement and allows couples time to understand one another. Engagement is a period where couples ensure they are ready for lifelong companionship before marrying, which is a permanent union between a man and woman. Factors like maturity, commitment, and character are important to consider when choosing a lifetime partner for a
Periodic table
The document summarizes the key people involved in the discovery and development of the periodic table of elements. It discusses Johann Dobereiner who discovered triads of elements, de Chancourtois who arranged elements in a helix, Newlands who proposed periodicity based on atomic mass, and Mendeleev who created one of the first recognizable periodic tables. It also mentions the contributions of Meyer, Ramsay, Moseley, and Seaborg in refining the table and adding new elements. The periodic table organizes elements based on electron configuration in their outermost shells and exhibits trends in properties from atomic radius to metallic character across the table.
Kinematic equations
The document discusses kinematic equations that describe uniformly accelerated motion. It provides the equations for final velocity, displacement, and initial and final velocities as functions of acceleration, time, and initial velocity or displacement. Examples are included to demonstrate solving for final velocity and displacement given values for acceleration, time, and initial velocity. The kinematic equations can be used to analyze motion under constant acceleration.
Velocity
Velocity is defined as the rate of change of an object's position over time, taking into account both speed and direction, and can be calculated using the formula that average velocity equals displacement over time. The document provides examples of calculating average velocity and discusses how velocity differs from speed by incorporating direction. It also defines acceleration as the change in velocity over a time interval and provides examples of calculating acceleration from changes in speed or direction over time.
Teenage concerns
This document discusses several key issues regarding teenage sexual health. It notes that adolescence is a formative time when habits are learned. Some of the most important issues are physical body changes during puberty, increased interest in sex due to hormones, and the need for comprehensive sex education about risks and consequences. Teenagers are exposed to sexual topics from many sources and need guidance on their values. The document outlines additional challenges such as dating pressure, risks of teenage pregnancy, importance of abstinence or safe sex education, and sexually transmitted diseases.
Sound energy
Sound is energy produced by vibrations traveling through matter such as air. Vibrations cause the surrounding air to produce sound waves that transmit the sound outward from its source. When these waves reach the ears, the brain processes the messages as sound. Sound travels faster through solids than liquids or gases due to the density of the medium. It also travels much slower than light, explaining why thunder is heard after lightning is seen. Protection from loud noises that can damage hearing includes avoiding very close or prolonged exposure to sounds and wearing ear protection during noisy activities.
Velocity
Velocity is defined as the rate of change of an object's position with respect to time and includes both magnitude (speed) and direction. It can be calculated using the formula: Average velocity = Displacement / Time. In the example, a girl travels 8 km in 15 minutes (0.25 hours) to get to school, so her average velocity is 32 km/h. Acceleration is the change in velocity over a time interval and is calculated as: Acceleration = Change in Velocity / Time Interval. It is a measure of how quickly an object's velocity changes. Both speed and direction must change for an object to be accelerating.
Mangrove swamps
Mangroves are woody plants that grow in coastal saline waters and muddy soils between land and sea in tropical and subtropical regions. They have complex root systems adapted for survival in wet, oxygen-poor conditions. Mangrove swamps support rich biodiversity and provide important ecosystem services like coastal protection, sediment stabilization, and nursery habitats for marine life. However, mangroves are threatened by habitat loss from aquaculture, development, pollution, and overharvesting of resources. Conservation efforts aim to protect remaining mangrove areas and restore degraded ecosystems.
Electron configuration
This document discusses the electron distribution in orbitals and sublevels across the first four principal energy levels. It provides the number of orbitals and electrons in each sublevel (s, p, d, f) as well as the total electrons per principal energy level. The first level contains 2 electrons in the s orbital. Each subsequent level adds new sublevels with increasing numbers of orbitals and electrons as you move further from the atomic nucleus.
