Question 13

Nerve tissue is composed of neurons and neuroglia.

Nerve tissue consists of neurons, which are the primary signaling cells, and neuroglia, which are the supportive connective tissue cells that maintain homeostasis, form myelin, and provide support and protection for the neurons.

A) Osteoblasts

Osteoblasts are specialized cells responsible for bone formation. They are not involved in nerve tissue composition and do not have a role in the central or peripheral nervous systems.

B) Neuroglia

Neuroglia, also known as glial cells, play a crucial role in supporting and protecting neurons. They are integral to the structure of nerve tissue and are essential for its functionality, making this option correct.

C) Osteocytes

Osteocytes are mature bone cells derived from osteoblasts and are involved in the maintenance of bone tissue. They are unrelated to nerve tissue and do not contribute to its composition.

D) Arterioles

Arterioles are small blood vessels that regulate blood flow and pressure in the circulatory system. While they may supply blood to nerve tissues, they do not make up the components of nerve tissue itself.

Conclusion

The correct answer is neuroglia, as these cells are fundamental to the structure and function of nerve tissue, providing necessary support to neurons. All other options fail to address the specific components of nerve tissue, as they pertain to different biological systems or functions unrelated to the nervous system.
