Block 2 Three Kinds of Muscle Flashcards
muscle cells are unique because they have the ability to blank
shorten
type of muscle in childbirth
smooth
muscle cell is aka blank
fiber
cytoplasm of muscl cell is aka
sarcoplasm
muscle cell plasma membrane is aka
sarcolemma
smooth er of muscle cell is aka
sarcoplasmic reticulum
this means soft, fleshy, meaty part of body which is muscle
sarco
two types of myofilaments
actin, myosin
type of epithelium in vas deferens
pseudostratified epithelium
skeletal muscle cells are generallly blank when transversely cut
round/oval
skeletal muscle has blank nucleus
multi
nuclei of muscle cell is placed where?
outside of the cell
there are blank of ct in muscle
layers
individual fascicles are enclosed by blank
perimysium
individual muscle fibers are enclosed by blank
endomysium
groups of fascicles are enclosed by blank
epimysium
outer epimysium is aka blank
deep fascia
tendons and ligaments are strong and resist stretch because they are made of blank and blank
collagen, dense regular ct
epimysium is aka blank in tendon
epitendineum
epimysium is aka blank in nerves
epineurium
fibers of tendon that actually insert into bone and are super strong
sharpeys fibers
ligament tear = pull = blank
strain/sprain
torn tendon has blank that remove injured cells
macrophages
torn tendon has blank that produce collagen to bridge the injured tendon
fibroblasts
macrophages come from blank
monocytes
myosin filament slides into the blank band during the sliding filament theory in muscle contraction
a
area between z lines area aka blank and can shorten and lengthen
sarcomere
during muscle contraction, these bands shorten
i, h
during muscle contraction, this band does not change
a
membrane that dips into the membrane of the skeletal muscle and is involved in action potentials
t tubules
three types of cardiac muscle
contractile cells, pacemaker cells, conduction cells
ventricles and atria have the blank type of muscle cells
contractile
sa and av nodes have blank type of muscle cells
pacemaker
bundle of his and purkinje fibers are this type of cardiac muscle
conduction
contractile cells of heart are blank unlike other cells
striated
heart only has this layer of muscle
endomyseum
heart is filled with blank
capillaries
cardiac muscle fibers blank unlike skeletal muscle
branch
the longitudinal longitudinal part of intercalated disc has blank junctions
gap
transverse part of intercalated disk has blank junctions
tight adherent
gap junction is aka blank
nexus
at the z lines, where actin filaments bind to proteins of the membranes there is a large spot compared to zonula and macula adherens called blank
fascia adherens
cardiac muscle does not have the ability to bring enough calcium about to make a contraction because it has an under developed blank compared to skeletal muscle
sarcoplasmic reticulum
lack of calcium in heart leads to blank heartbeat
weak
too much calcium in heart leads to blank heartbeat
fast irregular
