NERVOUS SYSTEM ANATOMY

Nerve impulses are waves of chemical and electrical signal change that is conducted along the membrane of a neuron, which is basically from sensory neuron to interneuron to motor neuron.

Cytoplasm composes the bulk of cellular material and provides a suspension medium for organelles and free-floating molecules.

Motor neurons relay the processed message to the tissues in the body, such as the muscles for action.

Sensory neurons detect stimuli and transmit signals to the brain.

Myelin covers the axon, which speeds up the travel of the nerve impulses.

The synapse is a tiny gap between two adjacent neurons.

Neurons are the basic functional unit of structure and function of the nervous system.

Dendrites are thread-like structures that branches from the cell body.

The cell body is the largest part of a neuron.

The axon terminal is a feather-like fibers that is found at the far end of the axon and they pass on messages to the dendrites of other neurons.
