Central Nervous System
Spinal Cord
Made up of 31 segments
A pair of spinal nerves leaves each segment of the spinal cord.
Receptors in the skin send information to the spinal cord through the spinal nerves.
Neuron
Axons
Axons help conduct electrical signals
Dendrites
dendrites receive and process signals from the axons of other neurons
Cell Body
The cell body carries genetic information, maintains the neuron’s structure, and provides energy to drive activities.
Brains
Cerebrum
is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
Cerebellum
is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
Brainstem
acts as a relay centre connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.
