Muscles Flashcards
What are the 3 types of muscles?
Skeletal, Smooth, and cardiac
what are Ligaments?
Tissue that connects bone to bone
What are tendons?
Tough bands of connective tissue that joins muscle to bone.
what are Fascia?
connective tissue that covers, supports, and seperates muscles.
What is Tissue?
Masses of cells that have similar function and form
what is muscle tissue
a collection of cells that shorten during contraction, therefore creating tension that results in movement
What is Skeletal Muscle?
Muscles that are attached to bones vie connective tissue tendons
is Skeletal muscle fatigue-resistant?
No
What is smooth muscle?
Muscles surrounding body’s internal organs+ blood vessels, respiratory tract, Iris(eye), and gastrointestinal tract
Their contractions are…
Slow and uniform and can be sustained for a long period of time.
their activation is…
involuntary
is smooth muscle fatigue resitant?
Yes
What is Cardiac Muscle?
Found only in the heart, contracts the heart, and is very fatigue resistant.
What is epimysium?
the connective tissue surrounding the whole muscle
What is perimysium?
connective tissues surrounding each fascicle.
what is a fascicle?
perimysium wrapped muscle fibers
What is endomysium?
the connective tissue surrounding each muscle fibre
what is muscle fibre?
a muscle cell
The ability of muscle to respond to stimulus?
Irritability
Ability to transmit nerve impulses?
conductivity
ability to shorten in length?
Contractibility
ability to extend in length?
extensibility
