1

What inhibits primitive reflexes?

Frontal lobe development. This is why frontal lobe lesions can lead to loss of inhibition of these reflexes.

2

plantar reflex

dorsiflexion of large toe and fanning of other toes with plantar stimulation

3

Location of CN nerves

FA 477

4

Location of infundibulum

FA 477

5

location of mammillary body?

FA 477

6

location of CN nerves in midbrain/pons/medulla ETC

Rule of 4s
4 above pons (I-IV)
4 in pons (V-VIII)
4 in medulla (IX-XII)
4 CN nuclei

7

medial CN nuclei

III, IV, VI, XII "factors of 12"

8

Location of pineal body, superior and middle cerebellar peduncles

FA 477

9

Pineal gland function

1) melatonin secretion
2) circadian rhythms

10

Superior colliculi function

conjugate vertical gaze center

11

Inferior colliculi function

auditory

12

Parinaud syndrome

paralysis of conjugate vertical gaze due to lesion in superior colliculi

13

Parinaud syndrome causes

1) pinealoma
2) stroke
3) hydrocephalus
