A visceral afferent nerve fiber carries sensory information from internal organs (viscera) to the central nervous system. These fibers transmit signals related to various physiological conditions, such as pain, pressure, and stretch, from organs like the heart, lungs, and gastrointestinal tract. This information helps the brain monitor and regulate bodily functions, contributing to homeostasis.
What else can I help you with?
Pelvic splanchnic nerve contains?
Parasympathetic fibres arise from S2,S3,S4. Carry preganglionic parasympathetic and visceral afferent fibres from pelvic and genital organs.
What fiber transmits impulses to the central nervous system?
The fiber that transmits impulses to the central nervous system is called an afferent or sensory fiber. These fibers carry sensory information from receptors in the body to the brain and spinal cord, allowing for the perception of different sensations like touch, temperature, and pain.
What afferent neurons convey information?
Afferent neurons carry sensory information in the form of nerve impulses to the central nervous system. Efferent/motor neurons carry commands to effectors such as muscles and glands.
Afferent nerves are also called what?
Nerve cell called sensory neurons. An axon also known as a nerve fiber is a long, slender projection of a nerve cell, or neuron, that typically conduct electrical impulses away from the neuron's cell body.If the fibres which are the branched projections attach to the cell body of nerve cell are dendrites
What is the function of spinal nerves- afferent?
They carry nerve impulses from your sensory organs, like your eyes, to your brain, or your central nervous system (CNS). When your eyes see something shiny on the ground, your afferent nerves tell your brain what your eyes see. In contrast, efferent nerves carry nerve impulses from your brain to parts of your body. So, when you see something shiny on the ground, your brain tells you to pick it up and look at it. Efferent = "Exiting", the nerves impulses are exiting your brain. Afferent = the opposite
What is another word for sensory nerve?
Afferent nerve
Can a nerve fibre and nerve both carry sensory and motor impulse Why?
Yes, a nerve fiber can carry both sensory and motor impulses, depending on the type of nerve. A mixed nerve contains both sensory (afferent) and motor (efferent) fibers, allowing it to transmit signals in both directions: sensory information from the body to the central nervous system and motor commands from the central nervous system to the muscles. However, individual nerve fibers typically specialize in either sensory or motor functions.
Which type of nerve cell carries messages toward the brain?
Sensory neurons are the type of nerve cells that carry messages from sensory receptors towards the brain to process and interpret information.
What Nerve to the brain triggers pain?
Afferent nerves carry impulses to the CNS (central nervous system: brain/spinal chord).
Does the white rami communicans contain fibers of a preganglionic or postganglionic neurons?
Preganglionic because they are myelinated. FALSE
What is the bundle of nerve fibers that send messages to the brain which interprets them?
The bundle of nerve fibers that send messages to the brain for interpretation is called the sensory pathway. These pathways carry sensory information from the peripheral nervous system to the brain where it is processed and interpreted.
Whiat nerve the afferent or efferent instructs your brain to avoid touching something hot?
afferent.
