Question

EXPLAIN THE ALL PARTS OF BRAIN?

Answer 1

Brain :-) The most important organ in animals .

The brain is a central information processing organ.

It controls voulantry and involuntary movements of our body.

BRAIN IS DIVIDED INTO 3 MAJOR PARTS

1. FOREBRAIN

2. MIDBRAIN

3. HINDBRAIN

1.FOREBRAIN

>> Again forebrain is divided into 3 parts. i.e.

cerebrum

thalamus

Hypothalamus

All over function of forebrain are excitement, pleasure rage ,fear , expression. , emotional reaction, secretion of some harmones, regulation of sexual behaviour, and motivation.

Functions of thalamus

major co-ordination centre for sensory and motor signals

MIDBRAIN

Midbrain is located between thalamus and Hypothalamus.

An important canal cerebral aqueduct is passed through Midbrain.

The dorsal portion of Midbrain contains 4 lobes that collectively called as corpora quadrigemina.

MIDBRAIN + HINDBRAIN = BRAIN STEM.

HINDBRAIN

IT contains 3 parts.

pons

cerebellum

medulla oblengata.

Function of medulla oblengata.

Respiration

cardiovascular activities

gastric secretion

hope it helps you

Answer 2

Answer:

The brain has three main parts: the cerebrum, cerebellum and brainstem.

Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.

Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Right brain – left brain

The cerebrum is divided into two halves: the right and left hemispheres (Fig. 2) They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.

Not all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people.

Left and right hemispheres

The cerebrum is divided into left and right hemispheres. The two sides are connected by the nerve fibers corpus callosum.

Lobes of the brain

The cerebral hemispheres have distinct fissures, which divide the brain into lobes. Each hemisphere has 4 lobes: frontal, temporal, parietal, and occipital. Each lobe may be divided, once again, into areas that serve very specific functions. It’s important to understand that each lobe of the brain does not function alone. There are very complex relationships between the lobes of the brain and between the right and left hemispheres.
