Transmit impulses toward from the cell body
A
afferent/sensory neurons
B
axons
C
dendrites
D
astrocytes
Explanation: 

Detailed explanation-1: -Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

Detailed explanation-2: -Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. An extension or process called an axon carries impulses away from the cell body.

Detailed explanation-3: -Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.

Detailed explanation-4: -Typical neurons have several dendrites-branching processes that conduct impulses toward the cell body, and a single axon-a long straight process that conducts impulses away from the cell body. Axons are often referred to as nerve fibers.
