NEET BIOLOGY

Detailed explanation-1: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.

Detailed explanation-2: -Neurons are the nerve cells that transmit impulses. Supporting cells are neuroglia. The three components of a neuron are a cell body or soma, one or more afferent processes called dendrites, and a single efferent process called an axon. The central nervous system consists of the brain and spinal cord.

Detailed explanation-3: -There are in fact two types of motor neurons: those that travel from spinal cord to muscle are called lower motor neurons, whereas those that travel between the brain and spinal cord are called upper motor neurons.

Detailed explanation-4: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-5: -Final answer : The neurons which carry impulses toward the brain are sensory neurons.
