Question 1

Central nervous system

Answer 1

Comprised of the brain and spinal cord, allows the brain to connect with and communicate to the rest of the body.

Question 2

Spinal Cord

Answer 2

The spinal cord can be broken up into the upper spinal cord and the lower spinal cord. The upper spinal cord controls the upper limbs and the lower spinal cord controls the lower limbs.

Question 3

Peripheral Nervous system

Answer 3

Allows humans to interact with their environment, the central nervous system coordinates the peripheral nervous system The peripheral nervous system has the somatic and autonomic nervous system.

Question 4

Somatic Nervous system

Answer 4

Controls voluntary movements of the body, motor neurons communicate messages from the central nervous system to the particular muscle which the person wants to move.

Question 5

Autonomic Nervous system

Answer 5

Communicates messages from the central nervous system to the body’s non-skeletal structures such as organs. Although most things are involuntary thing such as breathing and blink can be voluntary.

Question 6

Sympathetic Nervous system

Answer 6

The sympathetic nervous system activates when the organism is under threat, preparing the organism for action.

Question 7

Autonomic nervous system

Answer 7

The autonomic nervous system is further broken up into the sympathetic and parasympathetic nervous system

Question 8

Parasympathetic Nervous system

Answer 8

The parasympathetic nervous system controls the freeze response and also controls homeostasis

Question 9

Frontal lobe

Answer 9

Speech, abstract thought, social skills and planning

Question 10

Parietal Lobe

Answer 10

Help people to perceive three dimensional objects

Question 11

temporal Lobe

Answer 11

Process auditory information

Question 12

Occipital Lobe

Answer 12

The occipital lobe is responsible for visual comprehension

Question 13

Broca’s area

Answer 13

Broca’s area at the front of the left frontal lobe which coordinates lips, tongue, and vocal chords and also helps people to understand grammar. Damage to this area results in Broca’s aphasia

Question 14

Wernicke’s area

Answer 14

Wernicke’s area is located in the left temporal lobe. This area is responsible for deciphering language and constructing grammatically correct sentences. People with damage to these areas may develop Wernicke’s aphasia.

Question 15

Spinal Reflex

Answer 15

a response to sensory stimuli

Question 16

Basal Ganglia

Answer 16

A group of structures in the brain that coordinate voluntary movement.

Question 17

Cerebellum

Answer 17

Located in our hindbrain, it stores previously completed tasks.

Question 18

Primary Motor Cortex

Answer 18

Located in each rear of the frontal lobe, It is responsible for the movement of muscles and voluntary movement.

Question 19

Limbic System

Answer 19

involves the amygdala, hypothalamus and midbrain. It is involved in memory, behaviour, emotion and behaviour.

Question 20

Hippocampus

Answer 20

Involved in the regulation and expression of emotion, it also helps with memory.

Question 21

Hypothalamus

Answer 21

Helps the body do actions that will help our survival such as running and fighting.

Question 22

Amygdala

Answer 22

The amygdala is involved in the expression of certain emotions, such as fear. The amygdala is responsive to fear and helps condition us to fear.

Question 23

Pre-frontal Cortex

Answer 23

Part of the cerebral cortex which connects and covers the brain. Involved in regulating emotion also helps us make good choices.
