A bundle of axons or dendrites bounded by connective tissue inside the CNS is:
Correct answer: B. Tracts
- A. Nerves
- B. Tracts
- C. Ganglia
- D. Nuclei
Explanation
Option B is correct.A bundle of axons or dendrites bounded by connective tissue inside the central nervous system (CNS) is called a tract. Tracts are bundles of nerve fibers that transmit signals between different parts of the CNS. They are composed of axons or dendrites that are bundled together by connective tissue. The connective tissue helps to protect the axons or dendrites and to keep them organized. Tracts are named according to the regions of the CNS that they connect. For example, the corticospinal tract connects the cerebral cortex to the spinal cord. The tract is named corticospinal because it connects the cortex (the outer layer of the brain) to the spinal cord.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
