Question

Nerve cell does not contain _________
A) Axon
B) Nerve endings
C) Tendons
D) Dendrites

Answer 1

A nerve cell or neuron is a cell that has electrical conductivity properties which when it is excited communicates information with other surrounding nerve cells. It is present in animals except sponges and is absent from plants, fungi and other lower organisms.

Complete answer:
Atypical nerve cell or neuron comprises a cell body (soma), dendrites and a single axon. Among them the soma is compact whereas the axon and dendrites are filaments that protrude from it. The axon consists of an axon terminal at its farthest end and this is where a signal can be transmitted across the synapse to another nerve cell. The signaling process has electrical as well as chemical properties.Neurons contain voltage gradients across their membrane which when changes generates an action potential. This potential travels along the axon and activates synaptic signals. Synaptic signals can be excitatory or inhibitory. Neurons are classified into three different types based on their function- sensory, motor and interneurons. The sensory neurons respond to effects that affect the sensory organs and send signals to the brain and spinal cord. Motor neurons receive signals from the brain and spinal cord and carry out different functions. The interneurons connect one neuron to the other in the brain or spinal cord.Tendons are a type of connective tissue that join muscles to bones.

So the correct answer is option (C) Tendons.

Note: Nerve cells or neurons are a very important part of the body which help us to decipher any changes in our environment. Thus proper functioning of the neuron is of utmost importance.
