MEDICAL PHYSIOLOGY

Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.

Detailed explanation-2: -When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron. 4. Eventually, the message reaches the brain.

Detailed explanation-3: -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.

Detailed explanation-4: -The pons and the medulla, along with the midbrain, are often called the brainstem. The brainstem takes in, sends out, and coordinates the brain’s messages.

Detailed explanation-5: -A sensory neuron transmits impulses from a receptor, such as those in the eye or ear, to a more central location in the nervous system, such as the spinal cord or brain.
