Flashcards in Brain Deck (16):
1

Cerebrum:

Largest/most prominent structure

interprets sensory impulses controls voluntary motor activity

regulates muscle tone, stores info in memory

develops emotional/intellectual thoughts

2

Cerebellum:

posterior to the cerebrum

separated from the cerebrum by the transverse fissure

divided into 2 cerebullar hemispheres



regulates motor movements

coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in SMOOTH and balanced MUSCULAR activity.

3

the 3 parts of the brainstem:

Mesencephalon/Midbrain

Pons

Medulla Oblogata

4

Define the brainstem:

posterior region hidden in the phalemic region

5

Cerebral Penducles:

stocks of growth of tissue that connect the cerebrum & midbrain

6

Cereuncles:

stocks of growth of tissue that connect the cerebellum & midbrain

7

Mesencephalon/midbrain

where the corpora quadrigemina are located

contains the superior colliculi- reflexs for visual stimuli
inferior colliculi: reflexs for audiotory stimuli


8

Pons:

elevated mass of tissue on the uentral surface

connect the cerebrum to the cerebellum, medulla, spinal cord

regulates breathing center

9

Medulla Oblogata:

column of tissue extends posteriorly from the pons & is continous w/ the spinal cord

regulates heart rate, breathing rate, blood vessel diameter

10

Brainstem:

superior region hidden in the phalemic region
all information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem

11

Carpus Callosum:

contians myelinated nerve fiber tracts that connect the 2 CEREBRAL hemispheres

12

Hypothalamus:

regulates the autonomic N.S. & pitutary gland

control of the bodily functions not consciously directed


controls centers for temp, food/water, sleep, endocrine

hormonal

13

Mamillary Body:

a region in the hypothalamus

control center for motor reflexes associated w/ EATING

14

Thalamus:

relay station for sensory impulses going to the cerebral cortex

15

Pineal Body:

secretes melanin, assists the hypothalmus in regulating sleep/wake cycles

secretes seratonin-happy chemical

16

Cirgulate Gyrus:

where emotions & behaviors are regulated
of the cerebral cortex
