Major Brain Divisions: Hindbrain, Midbrain, Forebrain
The human brain can be divided into three main parts: the Hindbrain, Midbrain, and Forebrain. Each division has its specific functions and structures.

Hindbrain
The hindbrain is the lower part of the brain and consists of three primary regions: the cerebellum, medulla, and pons.

Cerebellum
The cerebellum helps in maintaining balance, coordination, and fine motor skills. It's also involved in learning movements and cognitive functions.
Medulla
The medulla controls involuntary processes such as heart rate, respiration, and blood pressure. It is crucial for basic survival functions.
Pons
The pons acts as a bridge connecting different parts of the brain. It plays a role in sleep, arousal, facial expressions, and sensory processing.
Midbrain
The midbrain connects the hindbrain and the forebrain. It's associated with features like motor movement and auditory and visual processing.

Tectum
The tectum is concerned with the perception of auditory and visual stimuli.
Tegmentum
The tegmentum helps to regulate motor functions and is involved in several reflexive responses to visual and auditory stimuli.
Red Nucleus
The red nucleus controls the motor coordination of the body, especially the limb movement.
Forebrain
The forebrain is the largest part of the brain and includes the cerebrum, thalamus and hypothalamus.

Cerebrum
The cerebrum is responsible for many major functions including sensory perception, learning, memory, consciousness, and voluntary motor actions.
Thalamus
The thalamus is a relay center transferring sensory and motor signals to the cerebral cortex and regulating consciousness, sleep, and alertness.
Hypothalamus
The hypothalamus regulates essential biological processes including hunger, thirst, body temperature, and sleep. It also helps to control the body’s response to stress and regulates hormones.
