Answer:
The correct option is : C) simple cuboidal epithilium
Explanation:
The simple cuboidal epithelium consists of only one layer of cuboidal cells that have a cube-like shape and also appear square-shaped in cross-section. The nucleus of the cuboidal epithelial cell is large and is present in the center of the cell.
The simple cuboidal epithelium is commonly found in the lining of the kidney tubules and are responsible for the reabsorption of the nutrients, ions and water from the tubular fluid.
Medullary cavities
Bone marrow is the soft, spongy tissue that is located in the medullary cavities (centers) of certain large bones. Healthy bone marrow is an essential part of the body, as it contains stem cells that produce blood cells and the cells that make up the immune system.

For sensory information to be relayed the nerve cells should have an axon.
<u>Explanation</u>:
- Nerve cells or neurons play a critical role in transmitting signals from various sense organs of the body to the spinal cord where it is processed.
- Neurons have different parts - the dendrites which are tiny branches that receive incoming signals from the body, the nucleus, and the axon.
- The axon is a long fiber that is covered by a protective layer called myelin sheath. It is this structure of the nerve cell or neuron that helps transmit signals to the Central Nervous System of which the spinal cord is a part.
