Question

Explain in detail human brain for class 10

Answer 1

Answer:

The brain is one of the largest and most complex organs in the human body.

It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses.

The brain is made up of many specialized areas that work together:

• The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex.

• The brain stem is between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here.

• The basal ganglia are a cluster of structures in the center of the brain. The basal ganglia coordinate messages between multiple other brain areas.

• The cerebellum is at the base and the b

ack of the brain. The cerebellum is responsible for coordination and balance.

The brain is also divided into several lobes:

• The frontal lobes are responsible for problem solving and judgment and motor function.

• The parietal lobes manage sensation, handwriting, and body position.

• The temporal lobes are involved with memory and hearing.

• The occipital lobes contain the brain's visual processing system.

The brain is surrounded by a layer of tissue called the meninges. The skull (cranium) helps protect the brain from injury.

Answer 2

$\huge{\mathfrak{Brain}}$

Brain is the largest part of the central nervous system.

It is about 1200cm³ - 1400cm³ in volume in an average human

Brain is a fleshy mass of many nerves connected to each other

The brain is divided into Fore Brain,Mid Brain and Hind Brain

Protection of Brain:

Brain is present inside a bony box called cranium which protects it from any mechanical injury. The cranium has deposits of calicum compounds making it durable and unbreakable.

Cerebro Spinal fluid is present in brain whose function is to protect the brain from shock

Classification of Brain:

ForeBrain

• The foremost part of the brain
• It is divided into two spherical parts called Cerebral Hemispheres
• It is estimated about a trillion nerves are present
• Forebrain is further divided into: Optic Lobes and Cerebrum
• Many Lobes are present here which correspond to the sensory organs and glands

MidBrain

• The connection between Hind Brain and Forebrain
• It consists of Cerebral Peduncles and Substantia Nigra
• Centres for auditory and visual reflexes

HindBrain

• The most posterior part of the Brain
• It is divided into cerebellum,medulla and pons
• Medulla is one of the most important parts of the brain
• Sites for involuntary functions
