Explanation

• Forebrain is also known as the cerebrum.
• It is the largest part of the brain.
• It is responsible for higher cognitive functions such as thinking, perception, and voluntary actions.

Explanation

The Medulla oblongata is the part of the brainstem that controls involuntary reflex actions, such as:

• Blood pressure
• Heartbeat
• Peristalsis (movement of food through the digestive system)
• Rate of respiratory movements
• Contraction and dilation of blood vessels

Explanation

• The pons is a bridge-like structure that links different parts of the brain.
• It connecting the midbrain to the medulla oblongata.

Explanation

The Hindbrain is divided into three main parts:

• Medulla Oblongata (controls breathing, heart rate, and blood pressure)
• Pons (involved in controlling sleep and arousal)
• Cerebellum (coordinates movement, balance, and learning)

Explanation

• The Midbrain is the smallest part of the brain, connecting the forebrain to the hindbrain.
• It plays a crucial role in auditory and visual processing, as well as body movement and coordination.

Explanation

The Hypothalamus lies at the base of the thalamus and plays a crucial role in regulating various bodily functions, including:

• Body temperature
• Feelings of hunger and thirst
• Hormone secretion
• Sleep-wake cycles
• Emotional responses

Explanation

The Forebrain, specifically the cerebrum, is responsible for controlling higher-level functions such as:

• Thinking
• Feelings
• Memory
• Hearing
• Seeing
• Speech
• Decision making

Explanation

• The Forebrain is the largest part of the brain and comprises two hemispheres: the left hemisphere and the right hemisphere. 
• The forebrain includes the cerebrum, which is responsible for processing sensory information, controlling movement, and managing higher-level cognitive functions such as thought, emotion, and memory.
