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.
