This topic covers the structure and function of muscles, including the different types of muscle tissue, muscle contraction, and movement.

Skeletal Muscle Structure: This includes detailed information about the different parts of skeletal muscles, including the anatomy of muscle fibers, tendons, and fascia, as well as the proteins that make up muscle fibers.
Muscle Fiber Types: There are several different types of muscle fibers, each with unique characteristics that determine its function. Understanding these differences is crucial for understanding muscle physiology.
Muscle Contraction: This topic covers the mechanisms behind muscle contraction, including the role of ATP, calcium ions, and actin and myosin fibers.
Muscle Energy Metabolism: This includes information on the different metabolic pathways that muscles use to produce energy, including the phosphagen, glycolytic, and oxidative systems.
Muscle Anatomy and Physiology of the Upper Body: This includes information on the muscles of the back, chest, shoulders, arms, and hands, and their respective functions.
Muscle Anatomy and Physiology of the Lower Body: This includes information on the muscles of the hips, legs, and feet, and their respective functions.
Muscle Innervation: This topic covers the nervous system's role in regulating muscle activity, including the neuromuscular junction and the role of motor neurons.
Muscle Adaptations to Exercise: This includes the physiological changes that occur in muscles as a result of exercise, such as hypertrophy, increased oxidative capacity, and improved muscle endurance.
Muscle Fatigue: This topic covers the causes of muscle fatigue, including both peripheral and central factors.
Muscle Injury and Repair: This topic covers the physiology of muscle injury and the process of muscle repair, including the role of satellite cells and the inflammatory response.
Muscle Biomechanics: This includes information on the forces exerted on the body by muscles, the principles of muscle mechanics, and the effects of muscle architecture on muscle function.
Aging and Muscle Function: This topic covers the changes in muscle structure and physiology that occur with aging, including sarcopenia and the loss of muscle strength and mass.
Muscle Diseases: This includes information on common muscle diseases, such as muscular dystrophy, myasthenia gravis, and ALS, including their causes, symptoms, and treatment options.
Muscle Assessment: This topic covers the different methods used to assess muscle function, including muscle strength testing, electromyography, and imaging techniques.
Muscle Pharmacology: This includes the different drugs used to treat muscle-related conditions, including steroid hormones, neuromuscular blocking agents, and muscle relaxants.
Skeletal Muscle: This type of muscle is attached to the bones of the skeleton, making it responsible for the movement of the body. It is striated in appearance, voluntary in action and accounts for nearly 40% of the body mass.
Smooth Muscle: This type of muscle is found primarily in the walls of hollow organs such as the stomach, intestines, and blood vessels. It is responsible for involuntary movements such as peristalsis, the movement of food through the digestive system, and the dilation and contraction of blood vessels.
Cardiac Muscle: This type of muscle is only found in the heart and is responsible for pumping blood throughout the body. It is also striated in appearance, but involuntary in action.
Laryngeal Muscles: These are the muscles that control the movement of the vocal cords, which are responsible for producing sound during speech.
Extraocular Muscles: These are the muscles responsible for the movement of the eyes, allowing for sight in different directions.
Respiratory Muscles: These are the muscles responsible for the act of breathing, specifically the diaphragm, intercostal muscles, and abdominal muscles.
Postural Muscles: These are the muscles responsible for maintaining posture and balance, such as the erector spinae muscles in the back.
Pharyngeal Muscles: These muscles are involved in the movement of food and liquid through the pharynx during swallowing.
Masticatory Muscles: These muscles are involved in the movement of the jaw during chewing, such as the masseter muscle.
Pelvic Floor Muscles: These are the muscles located in the pelvic region that support the bladder, uterus, and rectum, and are responsible for urinary and fecal continence.
"The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle."
"It permits movement of the body, maintains posture, and circulates blood throughout the body."
"The muscular systems in vertebrates are controlled through the nervous system."
"Some muscles (such as the cardiac muscle) can be completely autonomous."
"Together with the skeletal system in the human, it forms the musculoskeletal system."
"It permits movement of the body."
"It maintains posture."
"It circulates blood throughout the body."
