Which nerves carry impulses away from the spinal cord?
Cranial nerves, spinal nerves, and ganglia make up the peripheral nervous system. The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS.
Which neurons conduct impulses away from the spinal cord or brain quizlet?
Motor neurons, also called efferent neurons, transmit impulses from the brain and spinal cord to muscle and glandular epithelial tissue. Interneurons, also called central or connecting neurons, conduct impulses from sensory neurons to motor neurons.
Do efferent nerves carry nerve impulses from the spinal cord to the body?
The efferent fiber is a long process projecting far from the neuron’s body that carries nerve impulses away from the central nervous system toward the peripheral effector organs (mainly muscles and glands). A bundle of these fibers is called an efferent nerve (if it connects to muscles, then it is a motor nerve).
What carry impulses to and from the spinal cord?
Sensory neurons transmit nerve impulses from sense organs (eyes, ears, nose, tongue and touch) to the brain. They also carry nerve impulses to the brain and spinal cord. Motor neurons transmit nerve impulses from the brain and spinal cord to a specific area of the body.
Which type of nerve fibers carry impulses?
Efferent, or motor, nerve fibres carry impulses away from the central nervous system; afferent, or sensory, fibres carry impulses toward the central nervous system.
What neuron carries impulses to the CNS?
Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.
Which neuron carries nerve impulses towards its cell body?
dendrites
The dendrites carry impulses toward the cell body. The axon carries impulses away from the cell body. Axons and dendrites are sometimes called nerve fibers.
Which of the following carry impulses between hemispheres?
The cerebrum is divided into a right and left half (Figure above). Each half of the cerebrum is called a hemisphere. The two hemispheres are connected by a thick bundle of axons called the corpus callosum. It lies deep inside the brain and carries messages back and forth between the two hemispheres.
