Neuroanatomy Exam 4
1. true or false: the brainstem includes the thalamus, hypothalamus,
and cerebellum: false
2. brainstem:
connects to
contains fiber tracts or pathways for information ( and )
essential for functions (specialized nuclei)
origination of : diencephalon, spinal cord
many ascend,
descend vital
cranial nerves
(10)
3. direction terms in the brainstem:
dorsal =
ventral =
rostral =
caudal =:
posterior
anterior
superi
or
inferior
4. superior colliculus, inferior colliculus, tectum, cerebral aqueduct,
cerebral peduncles, crus cerebri, interpeduncular fossa, substantia nigra,
red nucleus-
: midbrain landmarks
5. rounded elevations on posterior side, visual pathway, send info to
thalamus; lateral geniculate body: superior colliculus
6. rounded elevations on posterior side, auditory pathway (send info to
medial geniculate body): inferior colliculus
7. refer to superior and inferior colliculus, back (roof) of midbrain: tectum
8. ventral to tectum, connects 3 and 4 ventricles: cerebral aqueduct
9. arm extending from pons, contain the crus cerebri: cerebral peduncles
10.fiber tract within cerebral peduncles, mainly descending, motor info:
crus cerebri
11.depression between peduncles: interpeduncular fossa
12. dark pigmentation, produces dopamine (activates basal ganglia circitry):
-
substantia nigra
13.circular motor centers, communicate with basal ganglia: red nucleus
1/9
, Neuroanatomy Exam 4
14.pons proper, trigeminal, pontomedullary junction: pons landmarks
15.belly of the pons: pons proper
16.where pons and medulla meet each other: pontomedullary junction
17.most inferior aspect of brainstem, top boundary is junction, bottom
bound- ary is basically foramen magnum: medulla
