Nervous System Lab Stuff Flashcards
three maters of meninges from superficial to deep
dura mater, arachnoid mater, pia mater
three parts of dura mater
falx cerebri, falx cerebelli, tentorium cerebelli
cavities filled with csf
ventricles
name the brain ventricles
two lateral, third, fourth
cerebrum is also called blank
telencephalon
how many hemispheres of brain
left and right
lobes of cerebrum
frontal, temporal, parietal, occipital, insula
the limbic system is composed of these three things
cerebrum, diencephalon, mesencephalon
epithalamus contains the blank and blank
pineal gland, choroid plexus
connects the two thalami
interthalamic adhesion
pituitary gland is connected to the hypothalamus by the blank
infundibulum
two parts of corpora quadrigemina
superior colliculi, inferior colliculi
made of the deincephalon, mesencephalon, pons, and medulla oblongata
brain stem
mnemonic for cranial nerve names
out on our table top are fruits very green veggies and hamburgers

cranial nerves seen in sheep
olfactory, optic
cranial nerves seen in human brain
II through XII
three white columns of spinal cord
anterior, posterior, lateral
four gray matter parts of spinal cord
posterior horn, anterior horn, lateral horn, gray commissure
six parts of spinal nerve
dorsal root, dorsal root ganglion, ventral root, dorsal ramus, ventral ramus, rami communicans
spinal nerves are formed by the fusion of blank and blank
dorsal, ventral roots
four nerve plexuses
cervical, brachial, lumbar, sacral
plexus that innervates muscles of neck and diaphragm
cervical
nerve that innervates diaphragm
phrenic
plexus that innervates the pectoral girdle and upper limb
brachial
plexus that innervates pelvis and lower limbs
lumbar
includes femoral nerve
lumbar
includes sciatic nerve
sacral
plexus that innervates pelvis and lower limbs
sacral
two branches of vestibulocochlear nerve
vestibular, cochlear
other nerve on top of vestibulocochlear nerve
facial
three parts of external ear
auricle, external acoustic meatus, tympanic membrane
three parts of middle ear
tympanic cavity, auditory tube, auditory ossicles
three auditory ossicles
malleus, incus, stapes
four parts of inner ear
cochlea, oval window, round window, vestibular complex
three parts of vestibular complex
utricle, saccule, semicircular canals
lacrimal refers to what
tears
two parts of fibrous tunic
sclera, cornea
external ear function
collect and direct sound waves to eardrum
middle ear function
amplify and transmit sound waves to inner ear
inner ear function
hearing and equilibrium
facilitates passage of sound waves into ear
auricle
transmits sound waves to middle ear
tympanic membrane
connects middle ear with nasopharynx
auditory tube
conduct vibrations to the inner ear
auditory ossicles
contains sensory receptors for sound
cochlea
stapes attaches to blank
oval window
provides equilibrium sensations
vestibular complex
three semicircular canals
anterior, posterior, lateral
three parts of vascular tunic
iris, ciliary body, choroid
two layers of neural tunic
pigmented, neural
layer of neural tunic with rods and cones
neural
Five parts of neural tunic
fovea, optic disc, lens, anterior cavity, posterior cavity
highest concentration of cones found in center of macula lutea
fovea
site of sharpest vision
macula lutea
place where all axons converge and exit eye as optic nerve (blind spot no cones or rods)
optic disc
focuses visual image on retina, divides eye into anterior and posterior cavities
lens
cavity filled with aqueous humor which is a cushion and transports nutrients and wastes
anterior cavity
cavity filled with vitreous humor which helps maintain shape of eye
posterior cavity
six extrinsic eye muscles
superior/inferior olique, superior/inferior/medial/lateral rectus
olfacotry bulbs and tracts are found on the blank
inferior surface of frontal lobe
2 layers of smooth muscle in the iris
pupillary sphincter, pupillary dilator
blank muscles attach to lens via suspensory ligaments
ciliary muscles
ciliary muscles extend posteriorly to the blank
ora serrata
innermost layer of the neural tunic
retina
