NEUROTRANSMISSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In sensory neurons, stimuli are received by the
A
axon
B
dendrites
C
cell body
D
myelin
Explanation: 

Detailed explanation-1: -The dendrites receive impulses from sensory receptors or other neurons and send them towards the cell body, which contains the nucleus. Impulses are then conducted along the axons full length away from the cell body to connect with the dendrites of another neuron, muscle, organ or gland of some kind.

Detailed explanation-2: -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-3: -Most sensory neurons are pseudounipolar, which means they have a single axon extending from the cell body that forms two extensions: the dendrites and the axon. The sensory neuron “begins” with the dendrites, as this is where the signal is received from the external environment.
