2.5.4 Nerve Tissue
- Nervous tissue senses stimuli and transmits signals from one part of a human to another.
- The functional unit of nervous tissue is the neuron, or nerve cell.
- It consists of a cell body and two or more extensions, called dendrites and axons.
- Dendrites transmit nerve impulses from their tips toward the rest of the neuron.
- Axons transmit impulses toward another neuron or toward an effector, such as a muscle cell.
