The document provides an overview of the skeletal and muscular systems. It discusses that the skeletal system includes bones, cartilage, joints, ligaments, and tendons that support, protect, and allow movement of the body. It also notes there are over 200 bones in the adult body. The document also outlines the three types of muscle tissue - skeletal, smooth, and cardiac - and their different functions. In summary, the document provides a high-level introduction to the key components and functions of the skeletal and muscular systems.

The muscular system is a complex network of tissues and organs responsible for movement, stability, and heat generation in the human body. Comprising more than 600 individual muscles, it enables various functions, including locomotion, posture maintenance, breathing, and circulation assistance. Muscles are composed of muscle fibers, which are elongated cells capable of contracting and relaxing to generate force. Skeletal muscles, attached to bones via tendons, facilitate voluntary movements, such as walking and lifting objects, under conscious control. Smooth muscles, found in organs like the digestive tract and blood vessels, perform involuntary functions like peristalsis and regulating blood flow. Cardiac muscle, exclusively present in the heart, sustains its rhythmic contractions to pump blood throughout the body. The muscular system works in coordination with the skeletal, nervous, and circulatory systems to ensure efficient movement and overall bodily function. Regular exercise and proper nutrition are essential for maintaining muscular health and strength throughout life.
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
It's fun to learn MUSCULAR SYSTEM...

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Today’s Warm-Up
Skeletal facts…
1. How many bones are in the average adult
human body?
2. How many bones does a baby have?
3. What/where is the longest bone on the body?
4. What/where is the smallest bone in the body?
206
Over 300!
The “femur” or thighbone
3 bones in the middle ear- stirrup, anvil & hammer
3. Function
The skeletal system includes bones and tissues
that are important for supporting, protecting, and
moving your body.
4. Parts of the skeletal system
• Bones (skeleton)
• Cartilage
• Joints: hold bone together
& mobility
• Ligaments & Tendons
5. Your skeletal system is made up of
the appendicular and axial
skeletons.
• The skeletal system
protects, supports,
and moves the body.
6. • The appendicular skeleton includes legs,
arms, feet and hands.
– allows for movement
– includes bones called girdles that connect
limbs to body
7. • The axial skeleton includes the skull, rib
cage, and spinal column.
skull
rib
breastbone
vertebra
– supports body and protects
tissues
– allows for limited movement
8. – cushions bones
– allows for smooth movement
(damaged cartilage leads to
joint pain)
– connects two bones
– As you age much of your
cartilage is gradually broken
down & replaced by bone
• Cartilage is connective tissue between bones.
9. Bones connect to form joints.
• Joints are places were two bones meet.
• There are three types of joints.
– Immoveable or
fibrous, which does not
allow for movement
fibrous joint
10. Bones connect to form joints.
• Joints are places were two bones meet.
• There are three types of joints.
cartillage
– Semi-moveable or cartilaginous, which allows
partial movement
11. Bones connect to form joints.
– Moveable or synovial,
which allows for
greater movement
• Joints are places where two bones meet.
• There are three types of joints.
12. • Ligaments are long bands of tissue that
connect bones across a joint.
ligament
13. Bones are living tissue.
• Bone is made of compact bone tissue and
spongy bone tissue.
Compact bone
Spongy bone
14.
15. • Compact bone is hard and dense.
– Osteocytes (bone cells) maintain compact
bone rings.
– Haversian canals allow blood vessels in the
bone.

16. • Spongy bone protects red or yellow
bone marrow.
– Red bone marrow produces blood cells.
– Yellow bone marrow is mostly fat.

19. • They provide movement
and force.
• There are 3 types of
muscle tissue:
- skeletal,
- smooth,
- cardiac
• Muscle tissue is made up
of muscle fibers
• Most muscles work in pairs
Muscles make up the bulk of the body
and account for 1/3 of its weight.
20. What are muscles made of?
• Thousands, or
even tens of
thousands, of
small fibers make
up each muscle.
21. Humans have three types of
muscle.
• The muscular system moves
substances throughout the body.
– bones of the skeletal system
– food through digestive system
– blood through circulatory system
– fluids through excretory system
22. – skeletal muscle
• There are three types of muscle tissue.
SKELETAL MUSCLE CARDIAC MUSCLESMOOTH MUSCLE
– smooth muscle
– cardiac muscle
23. Skeletal Muscles
• Skeletal muscles attach to bones by tendons
(connective tissue) and enable movement.
• Skeletal muscles are mostly voluntary
Feel the back of
your ankle to feel
your Achilles
tendon - the
largest tendon in
your body.
24. – move food through digestive organs
– empty liquid from the bladder
– control width of blood vessels
• Smooth muscle lines organs and is
involuntary.
Smooth muscle around this artery
allows the artery to regulate blood
flowby shrinking and expanding.
SMOOTH MUSCLE
25. – pumps blood throughout body
– contains more mitochondria than skeletal
muscle cells
• Cardiac muscle is found only in the heart.
CARDIAC MUSCLE
26. How the Heart is Different
• How is the heart different
from other muscles?
– It is part of both the
Muscular System and the
Circulatory System.
– It is responsible for
circulating blood throughout
the body.
– It has its own pacemaker
for rhythmic beating.
27. muscle fiber
Muscles contract when the nervous
systems causes muscle filaments to
move.
• Muscle fibers are cells of the muscular
system.
muscle
28. Muscle pairs:
Muscles are grouped together in pairs on your
skeleton
Relaxed or contracted:
When one muscle of a pair contracts, the other
relaxes
Pulling muscles:
Skeletal muscles only pull in one direction. For this
reason they always come in pairs. When one muscle
in a pair contracts, to bend a joint for example, its
partner then contracts and pulls in the opposite
direction to straighten the joint out again.
29.
30. Today’s Warm-up
• Muscle Trivia…
• How many muscles are in the average adult
human body?
• What is the strongest muscle in the body?
• What is the largest muscle in the body?
Approximately 650
Debatable, but many say the masseter (jaw).
The gluteus maximus in your rear end (buttocks).
