________ carry messages away from the brain to the muscles of the body.
Neurons are the basic unit of the nervous system. They carry information or impulses as electrical signals from one place to another in the body. There are 3 types of neurons: Sensory Neurons- Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS. Sensory neurons are also called afferent neurons. The nerves, spinal cord and brain work together to keep you aware of what's going on with the body and get messages out to the muscles and other body systems. Not all nerve me…ssages are handled by the brain though and so not all involve the spinal cord, the main path way to the brain from the body's nerves. Sends feedback information from somatosensory receptors back to the brain. (Blakeslee, 182) Communicates sensory information to the central nervous system and carries motor messages from the central nervous system to the muscles. Neurons are the basic unit of the nervous system. They carry information or impulses as electrical signals from one place to another in the body. Sensory Neurons- Sensory neurons carry electrical signals (impulses) from receptors or sense organs to the CNS. Neurons may have Dozens or even Hundreds of DENDRITES but usually ONLY ONE AXON. Sensory Neuron or Afferent Neuron Moving away from a central organ or point. Relays messages from receptors to the brain or spinal cord. Motor Neuron or Efferent Neuron  Moving toward a central organ or point. Relays messages from the brain or spinal cord to the muscles and organs. Nerve(s): a bundle of axons. (Kandel, 442) Bundle of conducting “nerve fibers” that transmit “impulses” from the brain or spinal cord to the muscles and glands, or inwards from the sense organs to the brain and spinal cord. (OxfordMed) Several axons running together outside the brain. An example, if you prick your finger the pain input is bounced back to the arm muscles to pull your finger away without the brain's input. A secondary message goes to the brain to notify it of the pain. A lot of the body nerve input does go through the spinal cord. Well not neurons, there are nerves in the spine. Neurons exist in the brain. With that being said, yes the spine is made of nerves that carry electrical impulses from every re…gion of the body to the brain and from the brain to the body. brain transmit messages to the body using neurons and spinal cord. ... Motor neurons carry messages away from the brain and back to the rest of the body. the central neurons s…ystem does many jobs at the same time. It controls all voluntary movement, such as speech and walking, and involuntary movements like blinking and breathing. Peripheral Nervous System: the portion of the nervous system outside the brain and spinal cord. It includes the nerves of the trunk and limbs. (Fields, 318) Brings messages from the “somatosensory receptors” to the spinal cord and brain. Carries messages from the brain and spinal cord to the muscles and glands.
