Assignment on Nervous system
Nervous System
Differences according to:
Motor neurons
Sensory neurons
Autonomic neurons
Function
Transmits impulses from the CNS which consists of the brain and spinal cord to muscles and glands elsewhere in the body
Transmits impulses inwards from the sense organs to the CNS
Located within the CNS, they transmit the electrical impulses generated by the stimuli to other nerves
Structure
Have Dendrites, Cell Body, Myelin Sheath, Node of Ranvier and Synaptic Knobs. The cell body is located at the top
Don’t have Dendrites, but have Cell Body, Myelin Sheath, Node of Ranvier and Synaptic Knobs. The cell body is located close to the middle region
Don’t have Dendrites, Myelin Sheath, or Node of Ranvier but have Cell Body and Synaptic Knobs. The cell body is located at the middle.
The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.
The nervous system includes both the Central nervous system and Peripheral nervous system. The Central nervous system is made up of the brain and spinal cord and The Peripheral nervous system is made up of the Somatic and the Autonomic nervous systems.
The Central nervous system
The central nervous system is divided into two major parts: the brain and the spinal cord.
The brain
The brain lies within the skull and is shaped like a mushroom. The brain consists of four principal parts: the brain stem the cerebrum the cerebellum the diencephalon
There are two types of matter in the brain: grey matter and white matter. Grey matter receives and stores impulses. Cell bodies of neurons and neuroglia are in the grey matter. White matter in the brain carries impulses to and from grey matter. It consists of the nerve fibers (axons).
The brain stem
The brain stem is also known as the Medulla oblongata. It is located between the pons and the spinal cord and is only about one inch
