Skeletal muscles
This presentation give the knowledge about the structure of skeletal muscle, the parts of skeletal muscle, physiology of skeletal muscle contraction.
skeletal muscle
This document summarizes the organization and structure of skeletal muscle. It describes that skeletal muscles are composed of bundles of long, cylindrical muscle cells called muscle fibers. Each muscle fiber contains thin filaments of actin and thick filaments of myosin that slide past each other during muscle contraction. Contraction occurs via a sliding filament mechanism where myosin heads hydrolyze ATP and attach to actin, generating a power stroke that shortens the muscle. Calcium release activates contraction by allowing the myosin heads to bind actin.
MUSCLES (THREE TYPES OF MUSCLES IN THE BODY)
Muscles is a contractile tissue which brings about movement.
Muscle cell responsible for our movement both visible and invisible, example walking, talking, bowel movement ,urination, breathing, heartbeats, the dilation and constriction of the pupils of our eyes and many other.
When we are still sitting or standing muscle cells keep us erect.
CONT...Muscles can be regarded as motors of the body.Muscles comprises about 40% to 50% (approximate) of body weight.There are approximate 650 muscles in body.Alternating contraction and relaxation of cells
Unit 6 muscular system
1. The muscular system has three main functions: produce movements, maintain posture, and generate heat.
2. There are three main types of muscle in the human body: skeletal, smooth, and cardiac muscle.
3. Skeletal muscle is attached to bones and controls voluntary movement, while smooth and cardiac muscles control involuntary functions like digestion and heart rate.
Muscular tissue and homeostasis
Muscular tissue contributes to homeostasis through body movements, moving substances through the body, and producing heat. There are three types of muscle - skeletal, smooth, and cardiac. Skeletal muscle is attached to bones and controls movement, smooth muscle is found in organs and blood vessels, and cardiac muscle is only found in the heart. Muscle fibers contract through a sliding filament mechanism where actin and myosin filaments interact through cross bridges to shorten the muscle. Calcium release triggers muscle contraction by exposing actin binding sites on the thin filaments.
muscular ppt.pptx
The document discusses the muscular system and muscular tissue. It covers three types of muscle tissue - skeletal, cardiac, and smooth muscle - and their distinct characteristics, locations, and functions. Skeletal muscle is composed of parallel bundles of fibers bound by connective tissue sheaths. Contraction occurs via the sliding filament model, where actin and myosin filaments slide past each other, shortening the sarcomere. Calcium release triggers the power stroke and ATP hydrolysis powers crossbridge cycling during contraction and relaxation. The document also examines muscle energetics and the role of cellular respiration, glycolysis, and the phosphocreatine shuttle in regenerating ATP during activity.
Functional and anatomy of skeletal muscle
The muscular system allows for body movement, maintenance of posture, respiration, communication, organ and vessel constriction, and heat production. There are three main types of muscle - skeletal, smooth, and cardiac. Skeletal muscle is striated, attached to bones, and responsible for voluntary movement. Smooth muscle is involuntary and found within organs and blood vessels. Cardiac muscle is found only in the heart. Muscles contract through a sliding filament mechanism where actin and myosin filaments interact in a cross-bridge cycle facilitated by calcium release from the sarcoplasmic reticulum.
Muscle Contraction and Movement_Enzymes.ppt
1. The document describes the molecular characteristics and mechanisms of muscle contraction. It discusses the structure and interactions of the contractile filaments actin and myosin.
2. The sliding filament theory is described as the mechanism where myosin heads bind to actin and hydrolyze ATP to slide along actin, causing muscle shortening.
3. The process of muscle contraction involves motor neuron stimulation, calcium ion release, actin-myosin cross-bridge formation, and sarcomere shortening through the sliding of actin and myosin filaments.

Muscular tissue.ppt
Muscle tissue consists of elongated muscle cells called fibers that have the ability to contract. The main types are skeletal, cardiac, and smooth muscle. Skeletal muscle is striated and voluntary, attaching to bones to enable movement. Cardiac muscle is also striated but involuntary, found only in the heart walls. Smooth muscle is non-striated and involuntary, surrounding hollow organs. All muscle tissues contain contractile filaments that slide past each other during contraction, but the structures differ between tissue types.
muscle_system.ppt
The muscular system is composed of three types of muscles - skeletal, cardiac, and smooth muscle. Skeletal muscle allows for movement by contracting and shortening. It is organized into fascicles containing bundles of striated muscle fibers. Muscle fibers contain myofibrils made up of overlapping actin and myosin filaments that slide past each other during contraction. Contraction is initiated when a nerve impulse causes calcium release and the heads of myosin filaments form cross-bridges with actin to generate force through the hydrolysis of ATP. Aging can lead to muscle loss but exercise can help build muscle mass. Disorders of muscle include muscular dystrophy and myasthenia gravis.
Muscular system

It describes the structure and function of skeletal muscle fibers and their organization into myofibrils, filaments, and sarcomeres. The sliding filament mechanism of muscle contraction is explained. It also describes the neuromuscular junction where motor neurons signal skeletal muscle fibers through the release of acetylcholine.
Molecular basis of Skeletal Muscle Contraction
The ppt aims to explain the molecular basis of skeletal muscle contraction and certain applied aspects of the same. Sources include Guyton and Hall's Textbook of Physiology (South-Asia edition, Vol. 2) and C.L. Ghai's Textbook for Practical Physiology.
Muscle physiology
- Muscle is divided into three types: skeletal, cardiac, and smooth. Skeletal muscle contractions are stimulated by nerves while cardiac and smooth muscles can contract independently.
- Skeletal muscle fibers are long, cylindrical, and multinucleated. They contain bundled myofibrils which are made of repeating sarcomere units. Sarcomeres contain thin actin and thick myosin filaments that slide past each other during contraction.
- Contraction is initiated by an action potential which causes calcium release from the sarcoplasmic reticulum. Calcium binds to troponin and tropomyosin, exposing actin binding sites for myosin heads to attach via ATP hydrolysis, causing sarcomere shortening and
T - Types of Muscle
Skeletal muscle is voluntary muscle that is attached to bones and controls movement. It comprises 40-50% of body weight and there are approximately 650 muscles. Skeletal muscle contracts and relaxes in alternating fashion using ATP to generate movement.
Cardiac muscle is involuntary muscle found only in the heart. It has a striated appearance and coordinates contractions to pump blood through the circulatory system. Cardiac muscle cells connect through intercalated discs to contract in a wave-like pattern.
Smooth muscle is involuntary muscle found in organs and passageways like the stomach, intestines, arteries and veins. It controls involuntary functions like digestion and regulates blood flow. Smooth muscle lacks striations and responds to chemical and neural stimuli for

Muscle physiology
This document provides an introduction to skeletal muscle structure and function. It discusses the following key points in 3 sentences or less:
Skeletal muscle forms about 50% of body weight, is voluntary and striated, and its main functions are tension development and shortening under nervous system control. Skeletal muscle is composed of bundles of muscle fibers which contain myofibrils made up of repeating structural units called sarcomeres, the basic contractile units of muscle. Each sarcomere contains thin actin filaments and thick myosin filaments arranged in a repeating pattern that gives skeletal muscle its striated appearance visible under electron microscopy.
Locomotion and movement
Locomotion is the voluntary movement of organisms that results in a change of position. It occurs through locomotory movements like walking, running, climbing, flying, and swimming. Muscles enable locomotion and have properties like excitability, contractility, extensibility, and elasticity. There are three main types of muscles - skeletal muscles which are striated and attached to bones, visceral muscles which are smooth and located in organs, and cardiac muscles which make up the heart. Skeletal muscles enable locomotion through contraction initiated by motor neurons in the nervous system.
10 muscular tissue
Muscular tissue is composed of muscle fibers that contract in response to electrical signals. There are three types of muscle tissue - skeletal, cardiac, and smooth muscle. Skeletal muscle is striated, voluntary, and attached to bones. It contracts through a sliding filament mechanism where actin and myosin interact powered by ATP hydrolysis. At the neuromuscular junction, a nerve impulse triggers the release of acetylcholine which binds receptors and generates a muscle action potential, causing contraction.

MUSCLE TISSUE.pptx
Muscle tissue is divided into three primary types - skeletal, cardiac, and smooth muscle. Skeletal muscle is organized into motor units controlled by the nervous system and allows for voluntary movement. Contraction occurs when calcium ions are released, causing the thin and thick myofilaments to interact via cross-bridges, sliding the filaments and shortening the sarcomere. The amount of tension produced depends on factors like sarcomere length, stimulation frequency, and number of motor units recruited. Energy for muscle contraction is obtained primarily through aerobic metabolism of fats and carbohydrates.
Anatomy and Physiology of Muscle by Prasanjit Shom.pptx
This document summarizes the anatomy and physiology of muscle. It describes the three main types of muscle - skeletal, smooth, and cardiac. It then focuses on the structure and function of skeletal muscle. Key points include that skeletal muscle is made of fascicles and fibers containing myofibrils and sarcomeres. Sarcomeres contain thin actin filaments and thick myosin filaments. Contraction occurs via a cross-bridge cycle in which calcium release allows myosin to interact with and pull on actin, shortening the muscle.
Structure of muscle
Skeletal muscle is composed of individual muscle fibers (myocytes) arranged in bundles and covered by connective tissue. Each muscle fiber contains contractile myofibrils made up of repeating sarcomere units. The sarcomere contains thin actin filaments and thick myosin filaments that overlap to allow muscle contraction when myosin heads attach to actin and move the filaments past each other using ATP energy. Other proteins such as tropomyosin, troponin and titin regulate the interaction of actin and myosin to control contraction.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 1. Structure of Skeletal Muscle Presentation by: Angela Holloman
- 2. Introduction • All activities that involve movement depend on muscles • 650 muscles in the human body • Various purposes for muscles for: – Locomotion – Upright posture – Balancing on two legs – Support of internal organs – Controlling valves and body openings – Production of heat – Movement of materials along internal tubes • Three types of muscles in the human body – Skeletal – Cardiac – Smooth
- 3. Skeletal Muscle • Skeletal muscles are muscles which are attached to the skeleton. • 40% of human body mass • Skeletal muscles are mainly responsible for locomotion, and voluntary contraction and relaxation.
- 4. Structure of Skeletal muscles • Skeletal muscles are composed of clusters of muscle cells. – Muscle fibers – Myofibers – Myocytes • A muscle consists of packages of muscle cells called fascicles • A muscle cell is long and spindle shaped
- 5. Structure of Skeletal muscles • Cell structure – Muscles cells contain many nuclei – The plasma membrane→ sarcolemma – The cytoplasm→ sarcoplasm – Length – ranges from 0.1cm to more the 30cm in length – Diameter – ranges from 0.001cm to 0.01cm in diameter • Myofibrils→ – elongated protein molecules – aligned in parallel arrangements – extend the full length of the cell.
- 8. Structure of Skeletal muscles • The myofibril consists of protein chains called myofilaments – Myofilaments have a symmetrical, alternating pattern of thick and thin elements.
- 9. Skeletal Muscle Myosin • Thick myofilament • consists of a large number of bundled myosin molecules aligned in overlapping arrays. • hexameric proteins with two identical heavy chains and two pairs of different light chains. – regulatory light chain (RLC) – essential light chain (ELC)
- 10. Skeletal Muscle Actin • The thin myofilament (F-actin, filamentous actin) – made up of two helically intertwined chains of G-actin (globular actin) units. • Other proteins that bind to the actin molecules: • Tropomyosin • The Troponin complex→ made up of three members
- 12. Contraction of Skeletal Muscle • The thick and thin filaments, along with their associated myofibril proteins, are responsible for muscle contraction. • How does muscle contraction work? – Influx of calcium ions in the cell • as a result of nerve impulses – troponin complex pulls tropomyosin molecules away from the G-actin subunits – Exposure of the myosin binding sites. – The heads of the myosin molecules can bind to the actin subunits, forming cross bridges. • active site in each myosin head disrupts the high-energy bond of ATP molecules • release of energy moves the myosin head towards the F- actin, • when contact is made with the actin subunits, the F-actin is pulled along, causing the myofilament to contract. • The coordinated contraction of all the myofilaments of all the muscle cells of a muscle, causes the entire muscle to contract.
- 14. Relaxation of Skeletal Muscle – Calcium ions are carried away from the myofilaments – Myosin- actin linkages loosen – The troponin complex and tropomyosin bind to the myosin binding sites on the F-actin subunits, • Myosin and F- actin myofilaments return to their original positions
