The Brain (unit 2 Pt 1)

Question 1

Brain stem

Answer 1

The central core of the brain. Responsible for automatic survival functions.

Question 2

Medulla

Answer 2

The base of the brain stem. Controls heartbeat and breathing

Question 3

Thalamus

Answer 3

The brains control center on top of the brain stem. It’s directs and receives messages from the sensory neurons and it replies to the cerebellum and medulla

Question 4

Reticular formation

Answer 4

A nerve network that goes through the brain stem to the thalamus. Plays a big role in arousal

Question 5

Cerebellum

Answer 5

The “little brain” at the back of the brain stem. Helps process sensory input, coordinate movement, balence and nonverbal learning

Question 6

Limbic system

Answer 6

The neural system that includes the amygdala, hypothalamus and hippocampus. Located below the cerebral hemisphere; associated with emotion and drive

Question 7

Amygdala

Answer 7

Two Lima-bean-sized neural clusters linked to emotion, especially aggression and fear

Question 8

Hypothalamus

Answer 8

Located just below the thalamus. Directs maintenance activities (like eating drinking and body temp) governs the endocrine system through the pituitary gland and it’s linked to reward and emotion

Question 9

Hippocampus

Answer 9

A neural center in the limbic system. Helps store explicit (conscious) memories of facts and events. Gets smaller as you age

Question 10

Cerebral cortex

Answer 10

Interconnected neural cells covering the cerebral hemispheres. It’s the body’s main control and info-processing center

Question 11

Frontal lobe

Answer 11

Part of the cerebral cortex located just behind the forehead. Involved in speaking, muscle movement, making plans and decisions

Question 12

Parietal lobes

Answer 12

Part of the cerebra cortex located at the top/back of the brain. It receives sensory input for touch and body position

Question 13

Occipital lobes

Answer 13

Part of the cerebral cortex at the very back of the brain. It receives information from the visual fields

Question 14

Temporal lobes

Answer 14

Part of the cerebral cortex located roughly above the ear. It processes auditory area such as receiving info from the opposite ear

Question 15

Motor cortex

Answer 15

An area at the back of the frontal lobe. Controls voluntary movement

Question 16

Somatosensory cortex

Answer 16

An area at the front of the parietal lobes. Resisters and processes body movement, sensation and touch

Question 17

Visual cortex

Answer 17

In the occipital lobes, receives input for your eyes

Question 18

Auditory cortex

Answer 18

In your temporal lobes, receives input from your ears

Question 19

Associated areas

Answer 19

Areas of the cerebral cortex that aren’t involved with primary motor or sensory functions, and instead are involved in higher mental functions like thinking,learning,remembering and speaking

Question 20

Broca’s area

Answer 20

Damage can effect speaking

Question 21

Wernicke’s area

Answer 21

Damage can effect understanding

Question 22

Plasticity

Answer 22

The brains ability to change, especially in childhood, by reorganizing after damage or building new pathways after an experience

Question 23

Neurogenesis

Answer 23

The formation of new neurons

Question 24

Pons

Answer 24

Help coordinate movement and sleep

Question 25

Aphasia

Answer 25

An impairment in language

Question 26

Left hemisphere

Answer 26

The “logic” hemisphere, dominant in language. With split brain it can talk about what it sees

Question 27

Corpus callosum

Answer 27

The large band of neural fiber that connect and send messages between the left and right hemispheres

Question 28

Split brain

Answer 28

A condition from surgery where the corpus callosum was cut, resulting in no communication between the two hemispheres

Question 29

Right hemisphere

Answer 29

The “artsy” side of the brain. With split brain it can’t get the mouth to talk about what it sees, but it can write it
