brain parts and functions

 The human brain is the main coordination center of the body. It is located inside the skull and on top of the spine. The brain is protected by the bone called the skull. 

The brain is surrounded by three membranes called meninges. The space between the membranes is filled with a cerebrospinal fluid that protects the brain from shock. The pairs of cranial nerves originate from the brain.

 

human brain

 

The brain is divided into three parts 

• forebrain, 
• midbrain, and 
• hindbrain.

Forebrain

Cerebrum - This is the main thinking part of the brain. It is responsible for reasoning, speech, the vision of intelligence, listening, and the use of information. There are distinct areas of association, where sensory information is combined with information from other receptors, as well as information that is already stored in the brain and found in the brain itself. voluntary actions controlled by the cerebrum.

parts of forebrain

Sensory area- receives sensory impulses from sensory organs such as skin, muscles, eyes, ears, and nose.

Association areas — Explain past experience and sensory information by other receptors.

Motor areas - send impulses to muscles and glands.

Olfactory lobes: It is responsible for detecting odor from various receptors.

Midbrain

The midbrain controls reflex movements of the head, neck, and trunk. It responds to visual and auditory stimuli. It controls the reflex movement of the eye, muscles, the size of the pupil, and the shape of the lens of the eye.

Hindbrain

It connects the spinal cord and the brain. Physician of three parts. Think of activities like walking in a straight line, riding a bicycle, lifting a pen. A part of the eunuch is called the cerebellum.

parts of hindbrain- cerebellum, ponds, and medulla oblongata.

Cerebellum

It regulates and coordinates the activities of various muscles. It maintains body posture and balance during various activities like walking, drinking, catching, etc.

Pons

It is located above the medulla and participates in respiration.

Medulla Oblongata

It was found to be continuous along the spine. It controls breathing, blood pressure (BP), and controls saliva and vomiting.

Functions of brain

• It coordinates body movements.
• It receives information from all the sensory organs of the body,
• It responds to impulses brought to the sensory organs.
• It stores information so that human behavior can be modified according to past experiences.
