amphiarthrosis: slight movement
diarthrosis: freely movable
what are the 4 names that we can call a muscle cell?
skeletal myocyte, myocyte, myofiber, muscle fiber
what triggers a muscle contraction, and what is required for a muscle to contract?
calcium and atp
neurons
what is the functional/anatomic classification of the humeroulnar joint?
functional: diarthrosis
anatomic: synovial/hinge joint
a gomphosis is what type of anatomical and functional classification of a joint? where can we find a gomphosis?
what is a sarcomere?
from one z disc to another z disc, made of actin and myosin
describe an isotonic eccentric contraction
muscle lengthens, example: triceps brachii as the humeroulnar joint is flexing
what is the speaking portion of a neuron? listening portion?
speaking axon, listening dendrite
name all of the muscles in the adductor muscle compartment
pectineus, adductor magnus/brevis/longus, gracilis
plane, ball and socket, hinge, condylar, saddle, pivot
endomysium: myofiber
perimysium: fascicle
epimysium: entire skeletal muscle
p: anterolateral surface of sacrum b.
d: greater trochanter of femur b.
a: lateral rotation of coxal j.
ependymal cells are what type of epithelial cells?
ciliated cuboidal epithelial cells
ID the 4 muscles of mastication, extra 300 points for naming attachments
temporalis, masseter, lateral/medial pterygoid
:)
name 6 joint movements
Pronation, Supination, Flexion, Extension, Adduction, Abduction, Plantar Flexion, Dorsiflexion, Elevation, Depression, Protraction, Retraction, Circumduction, Rotation, Eversion, Inversion
we have 7 shapes of muscles, what are they called?
fusiform, parallel, convergent, unipennate, bipennate, multipennate, circular
the linea aspera of the femur b. has quite a few muscles that attach to it, name all of them whether it's a proximal or distal attachment
vastus lateralis/medialis/intermedius, adductor longus/magnus/brevis
there are 5 neuroglial cells, what are they called and what do they do?
oligodendrocyte: myelin of axon in CNS, astrocyte: blood brain barrier, microglia: immune cell, ependymal cells: create CSF, schwann cells; myelin of axon in PNS
what is the most abundant support cell type in the brain?
astrocytes
show me was protraction of the scapula looks like, flexion of the glenohumeral j. looks like, and what dorsiflexion looks like
:)
describe how a skeletal muscle is formed from start to finish (start as microscopic as we can get)
:)
name all of the muscles that do lateral rotation for the coxal joint, which muscles do medial rotation?
lateral: gluteus maximus, piriformis, superior/inferior gemellus, obturator internus, quadratus femoris
medial: gluteus minimus/medius
explain what happens within the nervous system if you touch a hot stove?
sensory/afferent neuron picks up on signal takes it to CNS, interneuron communicates with efferent/motor neuron to respond to stimulus
the prime mover of humeroulnar flexion would be the ______, the antagonist would be the _______, a synergist would be ______
biceps brachii m. (long head/short head), triceps brachii (long/medial/lateral head), synergist: brachialis, deltoid m. pronator teres m.
