License Image All nerve cells (neurons) generally consist of 4 parts: the cell body, dendrites, an axon, and synaptic end bulbs. The nerve impulse flows in one direction. The dendrites receive incoming nerve impulses from other neurons, and the axon transmits the impulse to another neuron or receptor. The axon varies in length. It can […]

Synapse
License Image Nerve cells communicate with each other when the synaptic end bulb on the axon of one cell makes contact with a dendrite or cell body of another. Nerve cell impulses are conducted from one cell to another across this connection, called a synapse. The end bulb contains synaptic vesicles which are filled with […]
Sensory Input, Motor Response
License Image Neurons can be sensory (afferent) or motor (efferent) or association (interneurons). Sensory neurons carry information from receptors located throughout the body to the brain. Information from both the internal (inside the body) and external environments, in the form of light, heat, pressure, taste, and smell is detected by sensory neurons. Motor neurons carry […]
