Nervous system

Receives and transmits information.

1

Central nervous system

Consists of the brain and spinal cord. The brain is split into right and left hemispheres, which exhibit contralateral control and lateralization. The three major parts of the brain are the hindbrain, midbrain, and forebrain.

2

Hindbrain

The top part of the spinal cord; includes the medulla, pons, and cerebellum.

3

Medulla

Controls basic biological functions, such as breathing, swallowing, and balance.

4

Pons

Controls facial expressions, sleep, dreaming.

5

Cerebellum

Controls fine motor movements.

6

Midbrain

Coordinates basic movements with sensory information.

7

Forebrain

Large in humans; includes the cerebral cortex and subcortical structures such as the thalamus, hypothalamus, and basal ganglia.

8

Basal ganglia

Regulates muscle contractions and movements.

9

Thalamus

Incorporates and relays sensory information to the cortex.

10

Hypothalamus

Controls motivated behavior, such as eating, drinking, and sex.

11

Hippocampus

Helps process and receive long term and spatial memory.

12

Amygdala

Controls emotion and valuation of stimuli.

13

Cerebral cortex

Receives sensory information and transmits motor information.

14

Corpus callosum

A nerve tracts beneath the cortex that connects the two hemispheres of the brain and allows them to communicate.

15

Occipital lobe

Processes vision.

16

Temporal lobe

Processes sound.

17

Parietal lobe

An area of the cortex located directly behind the frontal lobe. It's functions include: processing sensory information from body parts, which includes touching, locating positions of limbs, and feeling temperature and pain; and carry out several cognitive functions, such as attending to and perceiving objects.

18

Frontal lobe

Control speech, learning, thinking, decision-making, and abstract thought.

19

Peripheral nervous system

Includes all nerves that spread through the body from the brain and spinal cord. The peripheral nervous system has two divisions.

20

Somatic division

Controls voluntary muscle movements and sense organs.

21

Autonomic division

Controls involuntary actions and the internal organs; divided into two parts.

22

Sympathetic nervous system

Gets the body ready for emergency action.

23

Parasympathetic nervous system

Becomes active during states of relaxation.

24

Limbic system

Refers to a group of about half a dozen interconnected structures that make up the core of the forebrain. Lindeke system structures are involved with many motivational behavior such as obtaining food, drink, and sex; with organizing emotional behaviors such as fear, anger, and aggression; and with storing of memories.

Made up of the amygdala, hypothalamus, thalamus, and Hippocampus.
