Nervous System

As we all know that humans are made up of cells, but for the nervous system, there are special cells known as neurons. The nervous system also controls our behavior, attitude, etc. The central nervous system contains the brain and spinal cord.

Brain The brain serves as the center of the nervous system. It controls the body, and it's divided into three main parts, the fore-brain, mid-brain, and hind brain.

Spinal Cord The spinal cord varies with the height of the human body, and it's different in all individuals. It's responsible for walking, running, sitting, etc. It transmits nerve impulses to the brain along with signals and messages from the body. Withdrawal reflex, also known as a spinal reflex, is the main function of the spinal cord, and it conveys information to the body in electrical form.

Neuron A neuron is a nerve cell that is the building block of the nervous system. It has the ability to control our minds and send signals to our brain when something happens. Neurons are specialized to transmit information throughout the body. They convey information through both chemicals and electricity throughout the body.

Peripheral Nervous System

Peripheral nerves are located throughout the whole body, and there are two types. One is the somatic nervous system, which carries information from sensory receptors in the eyes, ears, skin, etc. The autonomic nervous system carries messages from the brain and spinal cord to the muscles and glands.

Somatic Nervous System The somatic nervous system is under voluntary control. For example, touching something hot or tasting something bitter. For example, the reflex arc provides for automatic, simple, sudden responses.

Autonomic Nervous System The autonomic nervous system works by sudden, involuntary action. For example, a person in a coma. There are two further types. One is the sympathetic nervous system which deals with emergency systems related to sudden stress and emotions, such as the fight or flight response. The other is the parasympathetic nervous system which helps conserve energy, slows the heart rate and controls the digestive system.
