a.

Summary Introduction

To determine: The similarity and differences between autonomic ganglia and CNS nuclei.

Introduction: Central nervous system (CNS) comprises of brain and spinal cord. The complete CNS is made up of two major cells neurons and glial cells. Glial cells have a major contribution in the CNS and they provide support and insulation to the neurons. The ganglion is property of peripheral nerve cells and structures similar to ganglion in CNS is called as nuclei.

b.

Summary Introduction

To determine: The similarity and differences between adrenal medulla and the posterior pituitary gland.

Introduction: The glands are the secretory organs in which the cell produce chemicals are called as hormones and these hormones act as chemical messengers throughout the body. The glands can be either endocrine or exocrine. Adrenal gland and pituitary gland are both endocrine glands.

c.

Summary Introduction

To determine: The similarity and differences between axon terminal and varicosities.

Introduction: The neurons are important part of the coordination mechanism of the body. The neurons secrete signaling molecules called as neurotransmitters and these molecules can stimulate the target cell as well as other neurons.
