Very Short Question and Answers - Human Brain

The adult human brain weighs about 1.2 to 1.4 kilograms.

The three main parts are the forebrain, midbrain, and hindbrain.

The forebrain is the largest part of the brain.

The cerebrum is responsible for thinking, reasoning, intelligence, memory, voluntary actions, and interpreting sensory information.

The corpus callosum connects the two hemispheres of the cerebrum.

The hypothalamus regulates heart rate and body temperature, among other functions.

The thalamus acts as a relay centre for sensory information and is involved in awareness and attention.

The midbrain is located below the cerebrum and above the hindbrain.

The midbrain controls reflex movements of the eyes and ears, such as turning towards a loud sound.

Gyri are the raised folds and sulci are the grooves found on the surface of the cerebrum, increasing its surface area.

The hindbrain consists of the cerebellum, pons, and medulla oblongata.

The cerebellum controls balance, posture, and coordination.

The medulla oblongata controls involuntary actions such as heartbeat and breathing.

The pons acts as a bridge between different parts of the brain and controls facial expressions, sleep, and breathing rhythms.

The brain is protected by the cranium (skull bones), meninges (three membranes), and cerebrospinal fluid (CSF).

The three meninges are dura mater, arachnoid, and pia mater.

CSF acts as a shock absorber, provides nutrients, and removes waste from the brain.

The cerebrum is responsible for emotions like happiness and anger.

Turning your head suddenly toward a loud noise is a reflex controlled by the midbrain.

The hypothalamus controls sensations of hunger and thirst and regulates related behaviors.
