Question 1

Brainstem

Answer 1

The oldest part and central core of the brain, beginning where the spinal cord swells as if enters the skull; the brain stem is responsible for autonomic survival functions.

Question 2

Reticular Formation

Answer 2

A nerve network in the brain stem that plays an important role in controlling arousal.

Question 3

Thalamus

Answer 3

The brains sensory switchboard* located at the top of the brain stem, it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.

Question 4

Hippocampus

Answer 4

Linked to memory

Question 5

Pons

Answer 5

Pathway for nerve bundles between cerebellum and cerebrum.

Question 6

Cerebellum

Answer 6

“Little brain” - Processing sensory input and coordinating movement output and balance.

Question 7

Limbic System

Answer 7

Associated with movements such as fear mad aggression and drives such as those for food and sex.

Question 8

Amygdala

Answer 8

Components of Limbic system and are linked to emotion.

Question 9

Hypothalamus

Answer 9

Directs several maintenance activities (eating, drinking, body temp) helps control endocrine system via pituitary gland and is linked to emotion.

Question 10

Cerebral Cortex

Answer 10

The body’s ultimate control and information processing center.

Question 11

Glial Cells

Answer 11

Cells in the nervous system that support, nourish, ms protect neurons.

Question 12

Frontal Lobes

Answer 12

Involved in speaking and muscle movements and in making plans and judgements.

Question 13

Occipital Lobes

Answer 13

Includes the visual areas, ear h of which receives auditory information primarily from the opposite ear.

Question 14

Parietal Lobes

Answer 14

Receives sensory output for touch and body position.

Question 15

Temporal Lobes

Answer 15

Includes the auditory areas, each of which receives auditory information primarily from the opposite ear.

Question 16

Motor Cortex

Answer 16

Controls voluntary movements.

Question 17

Sensory Cortex

Answer 17

Registers and processes body touch and movement sensations.

Question 18

Association Areas

Answer 18

Involved in higher mental functions such as learning, remembering, thinking and speaking.

Question 19

Phineus Gage

Answer 19

Pole went through his head

Question 20

Aphasia

Answer 20

Impairment of language, usually caused by left hemisphere damage either to Broca’s area or to wernicke’s area.

Question 21

Broca’s Area

Answer 21

Controls language expression - directs the muscle movements involved in speech.

Broken Language - Slurred Speech

Question 22

Wernicke’s Area

Answer 22

Controls language reception - involved in language comprehension and expression.

If you say hola, I don’t understand

Question 23

Plasticity

Answer 23

The brains capacity for modification, as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development.

Question 24

Corpus Callosum

Answer 24

Large band of neural fibers connecting the two brain hemispheres and carrying messages between them.

Question 25

Split Brain

Answer 25

A condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mainly those of the Corpus Callosum) between them.
