What is the anatomy of muscle tissue?
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels. Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue.
What are the 4 types of muscle tissue?
Different types of muscle
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement.
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
- Cardiac muscle – the muscle specific to the heart.
What are the 3 types of muscles tissue and examples?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
What is muscle tissue in human body?
Skeletal muscle tissue consists of elongated muscle cells called muscle fibers, and is responsible for movements of the body. Other tissues in skeletal muscle include tendons and perimysium. Smooth and cardiac muscle contract involuntarily, without conscious intervention.
What organs are made up of muscle tissue?
Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.
What tissue can shorten itself?
Muscle tissue
Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force.
What is the strongest muscle in the human body?
masseter
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What is the difference between the 3 types of muscle tissue?
Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
What is the largest muscle of the body?
The gluteus maximus
The gluteus maximus is the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs.
Where is muscle tissue found in the body?
Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.
What is the main function of muscle tissues?
2. Support. Muscles of the body wall support the internal organs. As these muscles lose their tone, the internal organs of the abdominal-pelvic cavity may bulge outward as seen in some individuals as they age.
What can stimulate muscle tissue?
Muscle Spindles: monitor tension/stretch within muscles. Mechanism by which excitation of muscle cell membrane stimulates muscle cell contraction. Endplate has ACh receptors: ACh binds to receptors — causes endplate potential (EPP) and then a muscle action potential.
