Answer 14

motor control

Question 15

post central gyrus fnx?

Answer 15

physical sensation

Question 16

brocas area fnx?

Answer 16

regulates patterns of breathing and vocalization needed to for normal speech

Question 17

LAteral corticospinal tract

Answer 17

a descending motor pathway that controls the muscles of the arms and legs.

Question 18

fasciculus gracilis

Answer 18

sensory from T6 down (basically the lower half of the body) for touch and proprioception. It transmits this information up to the thalamus and then later parietal lobe.

Question 19

Fasciculus cuneatus=

Answer 19

sensory from the neck down to T6 (basically the upper half of the body except for the head) for touch and proprioception. It transmits this information up to the thalamus and then later parietal lobe.

Question 20

Lateral spinothalamic tract =

Answer 20

it transmits pain and temperature information from the body from the neck down. It transmits this information up to the thalamus and then later parietal lobe.

Question 21

funx of glossopharyngeal CN

Answer 21

sense of taste to posterior 1/3 of tongue.

sensory to nasopharynx, oropharynx, and to the adenoid, palatine tonsils, auditory tube and middle ear

Question 22

parasympathetic fnx of glossopharyngeal CN IX

Answer 22

to the parotid gland

Question 23

Vagus sensory to the

Answer 23

laryngopharynx and larynx

Question 24

vagus motor

Answer 24

to muscles of the soft palate, pharynx and larynx

Question 25

vagus parasympathetic fnx

Answer 25

to chest organs and to GI tract associated organs from esophagus to mid transverse colon

Question 26

spinal accessory nerve function

Answer 26

motor to the SCM and trapezius

Question 27

hypoglossal nerve FNX

Answer 27

motor to muscles of the tongue

Question 28

Inferior salivatory nucleus=

Answer 28

neurons from here supply the Parotid salivary gland to help breakdown food in your mouth.

Question 29

Dorsal motor nucleus of Vagus=

Answer 29

neurons from here decrease heart rate (chronotropic events) and heart force (inotropic events).

Question 30

Tractus solitarius=

Answer 30

neurons from CNs 7, 9, and 10 related to taste synapse here. Also neurons associated with pressure in the aortic arch (10) and carotid (9) synapse here. If blood pressure is too high the tractus solitarius will attempt to lower it via the dorsal motor nucleus of Vagus and nucleus ambiguous.

Question 31

Nucleus ambiguous=

Answer 31

neurons leaving here decrease heart rate and force.

a motor nucleus

Question 32

Hypoglossal nucleus=

Answer 32

the beginning of CN 12.

Question 33

Accessory nucleus= the beginning of CN

Answer 33

11.

Question 34

Obex=

Answer 34

bottom tip of the fourth ventricle where the central canal forms

Question 35

Dorsal intermediate sulcus=

Answer 35

dorsal slightly lateral indentation of the spinal cord.

where it sits between the gracilis and cuneatus fasciculus

Question 36

Dorsal median sulcus=

Answer 36

dorsal midline indentation of the spinal cord.

Question 37

Olive=

Answer 37

it has involvement in cerebellar learning via the olivocerebellar pathway and in the auditory pathway.

Question 38

Pyramids=

Answer 38

they contain descending axons in the motor pathway.

Question 39

Decussation of the pyramids= t.

Answer 39

90% of the descending corticospinal fibers decussate at the medulla oblongata to give rise to the lateral corticospinal trac
