The Human Brain-by Aisha.Z

What is it?

The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains

The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1). The hindbrain controls the body's vital functions such as respiration and heart rate.

parts of the brain:

These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe. Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain.
 

1.Occipital lobe:

The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area 17, commonly called V1 (visual one).

2.Temporal lobe:

The temporal lobe is one of the four major lobes of the cerebral cortex. It is the lower lobe of the cortex, sitting close to ear level within the skull. The temporal lobe is largely responsible for creating and preserving both conscious and long-term memory.

3. Parietal lobe:

The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area in the skull. It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature. Damage to the parietal lobe may lead to dysfunction in the senses.

4.Frontal lobe:

The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behaviors. It is, in essence, the “control panel” of our personality and our ability to communicate. 

5.Cerebral cortex:

The cerebral cortex (plural cortices), also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. The cerebral cortex mostly consists of the six-layered neocortex, with just ten per cent consisting of allocortex.

6.Cerebellum:

The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.

7. Hypothalamus:

The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.

8.Thalamus:

The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex.

9.Pituitary gland:

The pituitary gland is a small pea-sized gland that plays a major role in regulating vital body functions and general wellbeing. It is referred to as the body's 'master gland' because it controls the activity of most other hormone-secreting glands. Pituitary gland tags...

10.Pineal gland:

The pineal gland is a small, pea-shaped gland in the brain. Its function isn't fully understood. Researchers do know that it produces and regulates some hormones, including melatonin. Melatonin is best known for the role it plays in regulating sleep patterns. Sleep patterns are also called circadian rhythms.

11. Amygdala:

The amygdala is a collection of cells near the base of the brain. There are two, one in each hemisphere or side of the brain. This is where emotions are given meaning, remembered, and attached to associations and responses to them (emotional memories). The amygdala is considered to be part of the brain's limbic system.

12.Hippocampas:

Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.

13.Mid-brain:

The midbrain or mesencephalon is the forward-most portion of the brainstem and is associated with vision, hearing, motor control, sleep and wakefulness, arousal (alertness), and temperature regulation. The name comes from the Greek mesos, "middle", and enkephalos, "brain".
