10.6 Notes

Question 1

Medulla

Answer 1

Comes off of the spinal cord; responsible for vital functions and reflexes, such as breathing, heartbeat, blood pressure, vomiting, coughing, sneezing

Question 2

Drugs that affect the medulla

Answer 2

Alcohol and opiates; can kill you

Question 3

Pons

Answer 3

Anterior to the medulla; Contains many axon tracts that cross over to the opposite side of your brain

Question 4

Reticular formation

Answer 4

Areas that consists of the medulla and pons; sends info down and out to the body, and up and out to the higher levels of the brain; involved in arousal, sleep, dreaming, focus, and comas

Question 5

Raphe system

Answer 5

Contains neurons from the medulla and pons; involved in arousal, sleep, dreaming, and comas

Question 6

Cerebellum

Answer 6

Involved in movement timing and precision; impaired when consuming alcohol; involved in learning and habits

Question 7

Mesecephalon

Answer 7

Midbrain; consists of the tectum, tegmentum, and superior and inferior colliculi

Question 8

Tectum

Answer 8

Roof of the midbrain

Question 9

Tegmentum

Answer 9

Sends sensory info to the spinal cord and forebrain

Question 10

Superior colliculus

Answer 10

Send visual info to the brain

Question 11

Inferior colliculus

Answer 11

Sends auditory info to the brain

Question 12

Substantia nigra

Answer 12

Sometimes considered part of the brain; produces dopamine, which is black; this part dies in Parkinson’s disease; involved in movement, inhibiting unwanted movements

Question 13

Brainstem

Answer 13

Made up of the medulla, pons, in the midbrain; does not include the cerebellum; the most important part of your brain to keep you alive; involved in salivation

Question 14

Results of damage to the brain stem

Answer 14

Death, coma, loss of taste, paralysis of gaze, facial paralysis, nystagmus, loss of temperature and pain, nausea and vomiting, deafness, inability to feel vibrations, paralysis, hiccups

Question 15

Prosencephalon

Answer 15

forebrain; includes the diencephalon and telencephalon

Question 16

Diencephalon

Answer 16

Consists of the thalamus and hypothalamus

Question 17

Telencephalon

Answer 17

Consists of the cerebral cortex, hippocampus and basal ganglia

Question 18

Cerebral cortex

Answer 18

Involved in thinking, planning, and having conscious memories; what makes you human

Question 19

Gyri

Answer 19

The bumps of the cerebral cortex

Question 20

Sulci

Answer 20

The grooves of the cerebral cortex

Question 21

Neocortex

Answer 21

The outermost layer of the cerebral cortex; send info to the deeper levels of the cortex

Question 22

Thalamus

Answer 22

Collection of nuclei; sensory relay station; sensory info is sent to the thalmus, which is then relayed to the proper location in the cerebrum, except olfaction

Question 23

Basal ganglia

Answer 23

Five on each side: globus pallidus, substantia nigra, putamen, subthalamic nucleus, and caudate nucleus; involved in movement, Parkinson’s and Huntington’s diseases, and OCD; sends and receives info from the frontal cortex

Question 24

Corpus striatum

Answer 24

Includes the putamen and caudate nucleus

Question 25

Rhombencephalon

Answer 25

Hindbrain; most posterior; consists of the medulla, pons, and cerebellum
