Upon completion of this lesson, students should be able to:

  • Explain different types of glandular system.
  • Differentiate endocrine and exocrine glands.
  • Identify different components of the nervous system with their function.



Glandular System

Those organs that produce enzymes or hormones and plays important role for metabolism of body are called glands. This is a short introduction note on glandular system which is an aggregate of endocrine and exocrine gland. Learn More

Human Brain

Brain is the processing center of a human body. It is protected inside cranium (also called brain box) in the skull. There are three layers of membranes (connective tissue) that covers the brain called meninges. Brain has grey matter outside and grey matter inside. Average surface area for the human brain is 2500 cm square. This note is the detailed description of human brain. Learn More

Peripheral and Autonomic Nervous System

Peripheral nervous system includes the nerves that arise from the brain and spinal cord. There are 31 pairs of nerves that arise from the spinal cord and called spinal nerve. They connect the organ system to the brain.This is a short note explanation of what peripheral and autonomic nervous system are. Learn More

Introduction to Nervous System

The system that receives and transmits the stimulus, to and from the brain is called nervous system. The cell that transmits the message one part of the body to the other part is called nerve cell or neuron. This is a short introduction on human nervous system. Learn More

Spinal cord and Reflex actions

Spinal cord is the ling cylindrical part of CNS. It is present in neural canal of vertebral column. Spinal cord acts as the main center for reflex actions. Spinal cord acts as a link between spinal nerves and brain. Thus it participates in conscious actions. This note explains the anatomy and functions of the spinal cord. Learn More


Hormones are the chemical substances secreted by the endocrine and hetrocrine glands. They are the chemical messengers of the body and affect the growth and metabolic activities of targeted cells.
