Question 2

Which cranial nerves originate from the medulla oblaganta?

Answer 2

9,10,11 and 12

Question 3

What does the oculomotor control?

Answer 3

Eyeball movement, position of eyeball and pupil constriction

Question 4

Which cranial nerves originate from the pons?

Answer 4

5, 6, 7 and 8

Question 5

Which cranial nerves originate from the midbrain?

Answer 5

Cranial nerve 3 and 4

Question 6

Which cranial nerves arise from rostral midbrain?

Answer 6

Cranial nerve 1 and 2

Question 7

Anterior median fissure

Answer 7

Cross section of spinal cord that continues in the brain stem

Question 8

Pontine nucleus

Answer 8

Relays information from the cerebrum to the cerebellum

Question 9

Cerebral peduncles

Answer 9

Stalks connecting cerebrum to the midbrain. Consists of motor tracts of the corticospinal, corticobulbar and corticopontine axons to the midbrain and spinal cord

Question 10

Inferior olivary nucleus?

Answer 10

In the olives of the medulla obloganta and receives input from superior structures of the cerebral cortex, red nuclei and from the spinal cord. It regulates cerebellar neurons for motor learning (muscle memory)

Question 11

Constituents of medulla

Answer 11

Olives and pyramids

Question 12

Enteric centre

Answer 12

Nuclei in medulla to induce vomiting

Question 13

What is the medullary rhymic centre?

Answer 13

Nuceli in medulla and pons which is the respiratory centre

Question 14

What is the deglutition centre?

Answer 14

Promotes swallowing of food from oral cavity into pharynx

Question 15

What is the medullary rhythmic centre?

Answer 15

Nuclei in medulla and pons which is the respiratory centre

Question 16

What is the cardiovascular centre?

Answer 16

Nuclei in medulla which regulates inotropy and chronotropy and diameter of blood vessels

Question 17

What is the CNS nuclei?

Answer 17

Collection of cell bodies

Question 18

What are local circuit neurons?

Answer 18

Neurons which have an axon and dendron close to the cell body. They receive input from somatic sensory receptors and provide input to the brain by interconnecting to coordinate rhythmic activity in specific muscle groups, such as alternating flexion and extension of the lower limbs during walking.
