Question

what are the following and where do you find them in normal body.
a)Axon. b) ciliated epithelium​

Answer 1

Answer:

a) Axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell bodySome axons may be quite long, reaching, for example, from the spinal cord down to a toe.

b) A region of epithelium consisting of columnar or cuboidal cells bearing hairlike appendages (see cilium) that are capable of beating rapidly. Ciliated epithelia are found in the airways, the uterus and Fallopian tubes, the efferent ducts of the testes.

Answer 2

Answer:

Concept :

A fatty substance known as the myelin sheath covers axons. The term "nerve" refers to contiguous bundles of axons. Sensory neurons, interneurons, and motor neurons are the three different types of neurons found in animals. Interneurons, also known as association neurons, link sensory and motor neurons in the brain and spinal cord and carry stimuli. Motor neurons then transmit impulses from the brain and spinal cord to the muscle or gland that will respond to the stimulus. Sensory neurons receive stimuli from the outside environment.  It consists of a sparse intercellular matrix and a thin, continuous, protective covering of tightly packed cells. Throughout the body, epithelial tissues line the spaces in numerous internal organs, the inner walls of blood vessels, and the exterior surfaces of organs.

Explanation:

• Axons are the long, thin projections that neurons make from their bodies that assist in conveying nerve signals.
• The epithelium is one of the four fundamental forms of animal tissue, along with connective tissue, muscle tissue, and nerve tissue.The nerves are made up of bundles of axons.
• Simple columnar or cuboidal epithelium with cilia on their free surfaces makes up ciliated epithelium.
• The myelin sheath, a fatty substance layer, protects axons. A nerve is referred to as a group of bound axons.
• It can be found on the bronchioles' and oviducts' inner surfaces. It facilitates the flow of mucus or eggs in particular directions.
