Lecture 1

Question 1

Assessments of the neuro exam

Answer 1

1. Mental Status
2. Posture
3. Gait
4. CPs
5. Cutaneous trunci
6. Cranial nerves
7. Spinal Nerves
8. Pain

Question 2

Posture

Answer 2

position of the head relative to the body

Question 3

Ataxia is best seen from

Answer 3

behind the body

Question 4

conscious proprioception tests are done how?

Answer 4

knuckling over the foot and testing to see if it corrects within 1 second; animals should be placed squarely
-hopping, hemiwalking, or wheelbarrowing

Question 5

What does conscious propriocetion test?

Answer 5

afferent and efferent neural signals

Question 6

spinal reflexes in the thoracic limbs

Answer 6

withdrawal reflex

Question 7

pelvic limbs

Answer 7

patellar and withdrawal reflex

Question 8

reflexes vs responses

Answer 8

reflexes do not go to the cortex but responses do go to the cortex

Question 9

thoracic intumescence

Answer 9

C6-T2 - gives off nerves to the limbs

Question 10

pelvic intumescence

Answer 10

L4 - S1

Question 11

patellar reflex

Answer 11

hitting the patellar tendon looking for extension of the knee;
monosynaptic

Question 12

what does the patellar reflex test?

Answer 12

L4-L6 spinal cord segments and nerve roots; femoral nerve

Question 13

femoral nerve innervates what

Answer 13

quadriceps for extension of the stifle

Question 14

withdrawal reflex

Answer 14

polysynaptic (interneurons)

Question 15

what does the withdrawal reflex test?

Answer 15

Pelvic limb L6-S1 (sciatic nerve)
Thoracic Limb C6-T2 (multiple nerves)
muscles of flexion

Question 16

Just because you can have withdrawal… you may not have…

Answer 16

deep pain

Question 17

deep pain

Answer 17

positive sensation requires a cortical response such as crying biting and trying to get away

Question 18

other spinal reflexes

Answer 18

biceps, triceps, extensor carpi, cutaneous trunci, cranial tibial

Question 19

cutaneous trunci/panniculus reflex mechanism

Answer 19

pinch specific dermatones at the level of the hip
info travels up the spinal cord
travles to the lateral thoracic nerves
bilateral CT contraction

Question 20

What innervates the cutaneous trunci

Answer 20

lateral thoracic (C8 - T1)

Question 21

frontal lobe

Answer 21

motor cortex

Question 22

parietal lobe

Answer 22

somatosensory

Question 23

occipital

Answer 23

visual cortex

Question 24

temporal

Answer 24

auditory, behavioral

Question 25

cranial nerves that are supratentorial

Answer 25

CN I - II

Question 26

cranial nerves that are infrantentorial

Answer 26

CN III - XII

Question 27

CN I

Answer 27

Olfactory - senosory/smell

cell bodies in olfactory epithelium

Question 28

CN II

Answer 28

optic nerve; senosory for vision
