Nerves that carry impulses toward the cns only are ________ Rating: 4,2/10 1604 reviews

Nerves that carry impulses toward the central nervous system (CNS) are called afferent nerves. The CNS is made up of the brain and the spinal cord, and it is responsible for receiving and interpreting sensory information from the body, as well as initiating and coordinating voluntary and involuntary responses.

Afferent nerves are responsible for transmitting sensory information from the body to the CNS. This includes information about touch, temperature, pain, and other sensations. Afferent nerves are found throughout the body and are essential for our ability to sense and respond to our environment.

Afferent nerves have a very specific structure that allows them to transmit sensory information efficiently. They are made up of axons, which are long, slender fibers that extend from the nerve cell body. The axons are surrounded by a layer of myelin, which insulates and protects the axon and helps to speed up the transmission of impulses.

Afferent nerves are connected to sensory receptors, which are specialized cells that are sensitive to specific stimuli. For example, there are receptors in the skin that are sensitive to touch, and receptors in the eyes that are sensitive to light. When a stimulus activates a receptor, it sends an electrical impulse along the afferent nerve to the CNS.

The CNS then processes this information and sends out appropriate responses through efferent nerves, which carry impulses away from the CNS. This process of receiving and interpreting sensory information and initiating appropriate responses is essential for maintaining homeostasis and allowing us to interact with and respond to our environment.

Overall, afferent nerves are an important part of the nervous system, as they are responsible for transmitting sensory information from the body to the CNS. Without afferent nerves, we would be unable to sense and respond to the world around us.

Each Mauthner cell has an axon that crosses over, innervating stimulating neurons at the same brain level and then travelling down through the spinal cord, making numerous connections as it goes. Which neuron carries nerve impulses between neurons? They originated at the motor cortex of the brain. Why is it called trigeminal nerve? How should the nurse answer? The somatic sensory division carries signals from receptors in the skin, muscles, bones and joints. The effects of neurotransmitters released by somatic motor neurons may be either stimulatory or inhibitory.

nerves that carry impulses toward the cns only are ________

However, they communicated with the muscles they innervated through the motor neuron at the terminal. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon. The dorsal rami of all spinal nerves unite to form complex networks. An emergency medical technician is examining a trauma victim by shining a pen light into her patient's eye. Which of the following conducts impulses? These signals pass through the brain stem and the spinal cord ipsillaterially, to emerge at the ventral side of the spinal cord to terminate at the skeletal muscles or the smooth muscles. Sensory neurons typically have a long dendrite and short axon, and carry messages from sensory receptors to the central nervous system.
