Muscular System Flashcards
Muscular tissue has how many types?
3 types
Muscle cell is also known as?
Muscle fiber
more cylindrical, multinucleated & it’s stripped
Skeletal muscle
has one nuclei/cell, is branched & also striated /stripe
Cardiac muscle
has dark regions that are connective structures
Cardiac muscle
the dark connecting regions found in the cardiac muscles
Intercalated disc
spindle like muscle
Smooth muscle
connects one cardiac cell to another
Intercalated disc
it means “internal organs”
viscera
type of muscle we can find in the linings of our viscera
smooth muscle
what are the functions of muscular tissue?
producing body movements, stabilizing body positions,
moving substances within the body, generating heat
what are the properties of muscular tissue?
excitability, contractibility, extensibility, elasticity
muscle is attached to the bones by?
tendons
bone is attached to the bone by?
ligaments
a tissue covering that covers a fascicle
perimysium
a tissue covering that covers muscle bulk
epimysium
the tissue covering the muscle fiber
endomysium
dense sheet/broad band of irregular connective tissue that surrounds muscle
Fascia
outermost layer; separates 10-100 muscle fibers into bundles called fascicle/ full bulk
Epimysium
surrounds numerous bundles of fascicle
Perimysium
separates individual muscle fibers from one another
Endomysium
board flattened tendon
Aponeurosis
Muscle that encloses the mouth
Orbicularis oris
Muscle that turns the palm posteriorly
Ponator teres
pear-shaped muscle found in the gluteal region
Piriformis
Muscle that rotates and flexes the neck
Sternocleidomastoid
Muscle that lowers the angle of the mouth
Depressor labii inferioris
