|---|---|---|---|---|
|
What is elasticity?
Muscle cells recoil to a shorter length after being stretched and released.
|
What is the epimysium?
The connective tissue sheet that surrounds large sections of muscle.
|
What is the A-band?
The length of the thick filaments of a sarcomere.
|
What is moderate length?
This sarcoma length produces the optimal amount of force.
|
What is a muscle twitch?
A single brief stimulus of a muscle.
|
|
What are movement, to maintain posture and prevent movement, communication, control of body openings and passageways, heat production, and glycemic control.
Two functions of muscles.
|
What is tropomyosin?
The inhibitory protein on the thin filament that blocks binding sites of myosin so the muscle can relax.
|
What is the I-band?
The band that increases when a muscle lengthens.
|
What is the latent period?
The delay when the muscle is excited and where force is generated.
|
What is extensibility?
The characteristic of muscle cells to stretch in-between contraction.
|
|
What is excitability?
The characteristic of muscle cells to respond with electrical changes across the plasma membrane when stimulated by chemical signals, stretch, or other stimuli
|
What is a sarcomere?
The functional unit of muscle z line to z line.
|
What is the motor end plate?
The region of the sarcolemma under the presynaptic membrane.
|
What is a concentric contraction?
The contraction that occurs when a muscle is activated and the muscle length shortens.
|
What is the sarcoplasmic reticulum?
The calcium holding organelle in a muscle cell.
|
|
What is contractility?
The characteristic of muscle cells to shorted when stimulated allowing then to pull on bones and organs to create movement.
|
What is myosin?
The thick filament.
|
What is a cross-bridge?
This is formed when a myosin binds to an actin.
|
What is rigor mortis?
The stiffening of the body beginning three to four minutes after death.
|
What are the two terminal cistern and t tubule?
The three components of the triad found in the sarcoplasmic reticulum of muscle cells.
