Muscle Histology & Structure
Type of muscle that has a broad origin with fascicles extending toward a single tendon of insertion
Convergent
Name for the group of muscles that are located above the hyoid and help to elevate the hyoid
Suprahyoids (geniohyoid, mylohyoid, stylohyoid, digastric)
Type of neuroglial cell that performs phagocytosis
Microglia
Type of conduction performed by a myelinated axon
Saltatory conduction
The fight or flight division of the ANS
Sympathetic nervous system
Contraction that lengthens the muscle while it moves a load
Eccentric
Muscles that flex the hip and extend the knee
Quadriceps (quads - rectus femoris, vastus lateralis, vastus medialis, vastus intermedius)
Region of the diencephalon that contains the pineal gland
Epithalamus
Type of connective tissue that covers a fascicle
Perineurium
Division of the ANS that has a short postganglionic neuron and secretes acetylcholine
Parasympathetic nervous system
Connective tissue covering over the entire muscle
Epimysium
Innervated by the inferior gluteal nerve, this muscle extends the hip
Gluteus maximus
Gray matter horn that relays motor output
Anterior horn
Number of pairs of sacral nerves
5
Location of the olfactory cortex
Temporal lobe
Enzyme that degrades the neurotransmitter at the synaptic cleft
Acetylcholinesterase
Innervated by the abducens nerve, this muscle moves the eye outward
Lateral rectus
Lobe that contains the gustatory cortex
Insula
Which cranial nerve participates in taste sensation and exits through the stylomastoid foramen?
CN VII facial nerve
Sensory organ of the vestibular apparatus that detects angular (rotatory) acceleration/deceleration
Crista ampullaris
Activation of the myosin head and detachment of the cross bridge cycle would not be possible without this
ATP
Performs dorsiflexion of the foot at the ankle as well as inversion of the ankle
Tibialis anterior
Region of the brain stem responsible for coordinating auditory reflexes
Inferior colliculi (of corpora quadrigemina of tectum of midbrain)
Nerve from the brachial plexus that supplies deltoid and teres minor
Axillary
Components of the vascular tunic of the eye
Iris, ciliary body (ciliary process + ciliary muscle), and the choroid
