What carries impulses away from cell body?
An extension or process called an axon carries impulses away from the cell body. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.
What carries impulses away from the brain to the neuron?
Neurons are the nerve cells that transmit impulses. The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. There are three layers of meninges around the brain and spinal cord.
What the body does in reaction to a stimulus?
After your nervous system analyzes a stimulus, it causes a response. A response is what your body does in reaction to a stimulus. impulse. extensions called dendrites, and an axon.
Which is the longest cell in the human body?
the nerve cell
Complete Answer: – In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
Which sends impulses from the skin?
neurons
First-order neurons receive impulses from skin and proprioceptors and send them to the spinal cord. They then synapse with second-order neurons.
What is required to carry nerve impulses in the body?
A network of neurons is required to carry nerve impulses in the body.
What stimuli can we detect?
Broadly, sensory receptors respond to one of four primary stimuli:
- Chemicals (chemoreceptors)
- Temperature (thermoreceptors)
- Pressure (mechanoreceptors)
- Light (photoreceptors)

What transmits messages in form of impulses?
Neurons are also called nerve cells. They can be referred to as the functional unit of the nervous system. It is responsible for the transmission of messages in the form of electrical signals or impulses within the body. Each neuron consists of a cell body (soma), dendrites, and a single axon.
