Flashcards in 10.6 Notes Deck (25):
1

Medulla

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

2

Drugs that affect the medulla

Alcohol and opiates; can kill you

3

Pons

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

4

Reticular formation

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

5

Raphe system

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

6

Cerebellum

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

7

Mesecephalon

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

8

Tectum

Roof of the midbrain

9

Tegmentum

Sends sensory info to the spinal cord and forebrain

10

Superior colliculus

Send visual info to the brain

11

Inferior colliculus

Sends auditory info to the brain

12

Substantia nigra

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

13

Brainstem

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

14

Results of damage to the brain stem

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

15

Prosencephalon

forebrain; includes the diencephalon and telencephalon

16

Diencephalon

Consists of the thalamus and hypothalamus

17

Telencephalon

Consists of the cerebral cortex, hippocampus and basal ganglia

18

Cerebral cortex

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

19

Gyri

The bumps of the cerebral cortex

20

Sulci

The grooves of the cerebral cortex

21

Neocortex

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

22

Thalamus

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

23

Basal ganglia

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

24

Corpus striatum

Includes the putamen and caudate nucleus

25

Rhombencephalon

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