Study Notes

Structure of the Brain

Divided into three major divisions: Forebrain, Midbrain, and Hindbrain.
Forebrain includes the Cerebrum, Thalamus, and Hypothalamus.
Midbrain consists of the Tectum and Tegmentum.
Hindbrain is made up of the Cerebellum, Pons, and Medulla.

Major Parts of the Cerebrum

Frontal Lobe: Responsible for thought, problem-solving, judgment, behavior, and muscle movements.
Parietal Lobe: Focuses on language comprehension, sensory processing, and spatial awareness.
Temporal Lobe: Manages auditory and visual memories, speech, and language processing.
Occipital Lobe: Dedicated to vision processing and interpretation.
Sensory Cortex: Receives and processes sensory information from the body.
Motor Cortex: Controls and monitors bodily movement.

Special Areas in the Cerebrum

Wernicke's Area: Essential for understanding and formulating speech.
Broca's Area: Involved in producing speech and understanding language.

Cerebellum

Known as "The Little Brain," regulates balance, posture, and coordination.

Limbic System

Plays a key role in emotions and hormonal responses.
Major components include the Amygdala, Hippocampus, Hypothalamus, and Thalamus.

Brain Stem Components

Midbrain (Mesencephalon): Regulates movement, vision, and hearing.
Pons: Connects to the cerebellum, vital for posture and movement regulation.
Medulla Oblongata: Controls vital functions like heart rate and breathing.

Brain Study Methods

Computerized Axial Tomography (CAT): Combines multiple X-ray images to create a detailed brain structure image.
Electroencephalogram (EEG): Monitors electrical activity of the brain using external electrodes.
Magnetic Resonance Imaging (MRI): Utilizes magnets for detailed images of brain structure.
Positron Emission Tomography (PET): Tracks radioactive isotopes to visualize brain activity.

Endocrine System Overview

Regulates bodily processes via hormones produced by ductless glands.
Pituitary Gland: Known as the master gland, controls various endocrine functions.
Thyroid Gland: Secretes thyroxin, influencing metabolic activities.
Adrenal Glands: Secrete epinephrine/adrenaline for arousal in emergencies.
Pancreas: Produces insulin, regulating blood sugar levels.
Gonads/Sex Glands: Testes (androgen and testosterone) and ovaries (estrogen and progesterone) promote sexual development and function.
