MEDICAL PHYSIOLOGY

Detailed explanation-1: -For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move. These connections make up the way we think, learn, move, and feel.

Detailed explanation-2: -Cells of the nervous system, called nerve cells or neurons, are specialized to carry “messages” through an electrochemical process. The human brain has approximately 86 billion neurons. To learn how neurons carry messages, read about the action potential. Neurons come in many different shapes and sizes.

Detailed explanation-3: -Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Motor neurons control voluntary muscle activity, such as walking and talking, and carry messages from nerve cells in the brain to the muscles.

Detailed explanation-4: -Sensory neurons are the afferent limb of somatosensory neural pathways. The neuron consists of a cell body, axon, and dendrites. Dendrites are finger-like projections that receive sensory input and transmit the signal through the axon to the cell body.

Detailed explanation-5: -Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.
