Cerebral cortex is an important region of the cerebrum; it is also known as the grey matter of the brain. Grey matter is the region where nerve cells concentrate. These nerve cells are arranged as irregular folds. These irregular folds increase the surface area of the cortex. These cells of the cortex are connected with […]
The fore-brain or the cerebrum is the largest part of the brain and it makes about 85% of the brain. The folds in the fore-brain help it to fit into the skull. The main parts of the fore-brain are: cerebral hemispheres and basal ganglia. Cerebrum is the base of memory, intelligence and mind. It is
The brain is the central control system of the body, also called the master organ of the body. It lies in the skull (brain case) and protected by a bony box called cranium. It has three main parts: the fore-brain, mid-brain and hind-brain. The human brain works like a master computer. The brain processes the
Sensory neurons, also known as afferent neurons, carry signals from the receptor in the body towards the central nervous system. Dendrites of the sensory neurons collect the signals from the receptors in the skin, eye, nose and other sensory organs, and carry them towards the central nervous system. The stimuli are transferred to the cell

Motor neurons, also known as efferent neurons, are the connecting unit between the muscular system and the central nervous system. They carry information from the nervous system to the muscles. The signals are transmitted through the neurons to the effector organs where an impulse has to be generated. In case of muscles, these impulses can
In the nervous system, a synapse is a space between two neurons that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another cell (neural or otherwise). It provides a bridge between two neighbouring neurons or between a neuron and an effector organ; nerve impulses are transmitted by a chemical
Neuron or nerve cell is the basic unit of the nervous system. Neurons act as transmitters and receptors of nerve impulses. They carry information through electrical and chemical signals. Neurons are supported by a special tissue called the neuroglia. The main components of a neuron are: dendrites, cell body, node of ranvier and axon. The
The nervous system controls all the basic bodily functions and behaviour. That is why it is known as the principal organ system. The basic unit of the nervous system is a neuron. The two major parts of the nervous system are: the central nervous system and the peripheral nervous system. The central nervous system is

The male reproductive system is a set of organs which produce male gametes (sperm cells) and deliver them to the uterus of the female. The primary male reproductive organs are the testicles and scrotum. The testes or testicles generate sperms. The formation of sperms is activated by the hormone testosterone (male hormone). The sperms pass
