Nervous System

There are two main
Parts of the nervous system Central nervous system
• Made up of the brain and the spinal cord
Peripheral nervous system
• Made up of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system. These regions are all interconnected by means of complex neural pathways.

Central nervous system The

The cerebellum is the part of the brain that plays an important role in motor control and can possibly be involved with few cognitive functions such as attention and language. Does the following:

Regulates sense of balance. Coordinates voluntary muscle movement. Central nervous system The

The Cerebrum directs voluntary movement, sensory processing, language, communication, learning, and memory. o o



Temporal Lobe
-hearing and selective listening.
Occipital Lobe – visual processing center. Parietal Lobe – two regions that consist of perception and sensation cognition.
Frontal Lobe reward, attention, short-term memory tasks, planning, and motivation. Click icon to add picture

The Medulla
Oblongata transfer messages to the spinal cord and the thalamus in the brain from the body
It controls :


Heart Rate

Blood Pressure

Swallowing and digestion Peripheral nervous system

Nucleus o Contains genetic material Cell Body
 Contains the nucleus and other organelles
 Also known as compact area
 Receive stimuli
 Conduct impulses toward the cell body
 Carries impulses away from the cell body Axon Terminals

The end feet that make contacts with other nerve cells for the axon.

Neuron – The
Nerve Cell

The Basal Ganglia -

Peripheral nervous system

A region of the base of the brain that consists of three clusters of neurons (caudate nucleus, putamen, and globus pallidus) that are responsible for involuntary movements such as tremors, athetosis, and chorea.
The basal ganglia are abnormal in a number of important neurologic conditions, including Parkinson's disease and
Huntington's disease.

Peripheral nervous system

Sensory Divison
 Sends information to the central nerve system.
