Module 12: Cerebral Cortex ; Parts of the Brain

Question 1

Brain Stem

Answer 1

Connects the cerebrum to the spinal cord.
Consist of the midbrain,medulla oblongata, and the pons.
Coordinates & relays motor signals
Controls supporting nervous system functions such as: breathing, heart rate, blood pressure, temperature, digestion.

Question 2

Cerebellum

Answer 2

Base of the skull
Controls motor movements coordination, balance, equilibrium, and muscle tone.
Relays info. between the muscles and the cerebral cortex for motor control.
Also incharge of some memory for relex motor acts.

Question 3

Occipital Lobe

Answer 3

Rear of the cerebral cortex.
Main center for visual processing (color, shape, & distance)
Motion detection

Question 4

Visual Cortex

Answer 4

Receives visual input form the retina (gets interpreted in the occipital lobe)
Rear part of the occipital lobe

Question 5

Parietal Lobe

Answer 5

Back-top of the brain.
Involved in the reception & processing of sensory info. from the body
Orientation & perception
Attention & language

Question 6

Frontal Lobe

Answer 6

Front of the brain (behind the forehead.
Involved in movement, making decisions, problem solving, & planning.
+ higher order functions, concentration & attention span, reasoning/critical thinking, judgement, impulse control, habitual memory and motor activities, emotional response & empathy, expressive language & meaning

Question 7

Temporal Lobe

Answer 7

Side of the head (above ears)
Organizes auditory information, production of language & speech, & emotional responses
comprehension of sound and speech ; processes auditory information
Aids in language and reading

Memory, hearing, sequencing, organization

Question 8

Medulla

Answer 8

Top of the brainstem Controls heartbeat & breathing

Question 9

Pons

Answer 9

Above the Medulla
Coordinates movement and other autonomic functions.
Responsible for nonsexual arousal, sleep, and relaying information between the cerebellum & cerebral cortex

Question 10

Reticular Formation

Answer 10

Throughout the brainstem
Essential for arousal (sleeping,walking, and pain perception)
Regulates awareness & attention
Filter incoming stimuli to send to other brain areas

Question 11

Thalamus

Answer 11

Above the brainstem

Sensory info. in regards to hearing, seeing, touching, and tasting

Question 12

Hippocampus

Answer 12

Limbic System; Around the Medulla

Central to learning & memory

Question 13

Amygdala

Answer 13

Limbic System; End of the Hippocampus
memory consolidation and emotion (fear and aggression)
Processes long term emotional memories
Helps recognize and avoid future threats

Question 14

Cerebrum & Cerebral Cortex

Answer 14

Cerebrum: both hemispheres
Cerebral Cortex: outermost layer
Plays a role in perception, awareness, thought, memory, language, & consciousness

Question 15

Motor Cortex

Answer 15

Rear of Frontal Lobe
Control voluntary movement & sends messages to the body from the brain
Part of the Frontal lobe

Question 16

Sensory Cortex

Answer 16

Part of the parietal lobe
Right behind the motor cortex
Processes incoming sensations such as pain & temperature

Question 17

Auditory Cortex

Answer 17

Middle of the Temporal Lobe
Receive input from the auditory pathways in the brainstem & thalamus
* Pitch & Volume *
