Nerve cell does not contain.
(a) axon
(b) nerve endings
(c) tendons
(d) dendrites
Solution
A neuron, also known as a nerve cell, is an electrically excitable cell that communicates with other cells through synapses, which are specialized connections between cells. Except for sponges and placozoa, it is the main component of nervous tissue in all animals. Nerve cells do not exist in plants or fungi.
Complete answer:
Neurons are usually divided into three categories based on their function. Sensory neurons send signals to the spinal cord or brain in response to stimuli such as touch, sound, or light that affect the cells of the sensory organs. Everything from muscle contractions to glandular output is controlled by motor neurons, which receive signals from the brain and spinal cord.
A neuron's cell body (soma), dendrites, and a single axon make up a typical neuron. In most cases, the soma is compact. The filaments that protrude from it are the axon and dendrites. Dendrites usually have a lot of branches and extend a few hundred micrometers from the soma. The axon leaves the soma at a swelling known as the axon hillock and travels up to 1 meter in humans and more than 1 meter in other species.
It can branch, but it usually keeps the same diameter. Axon terminals are located at the farthest end of the axon's branches, where the neuron can send a signal across the synapse to another cell. Dendrites and axons are not always present in neurons. When a cell is undifferentiated, the term neurite is used to describe either a dendrite or an axon.
Tendons are not found in nerve cells. A tendon is a strand of fibrous connective tissue that connects muscle to bone. Tendons are bright white and located between bone and muscle. They're made of connective tissue, which contains a lot of strong collagen fibers.
Thus, the answer is Option C: Tendons.
Note: The dendrites and soma of most neurons receive signals and send them down the axon. Signals cross from one neuron's axon to another's dendrite at the majority of synapses. Synapses, on the other hand, can connect one axon to another or one dendrite to another.
