Study Notes
Endocrine System: Gland and Hormone Functions
- Review the pancreas, adrenal glands, stomach, anterior pituitary, thyroid gland, and hypothalamus.
- Understand which hormones each secretes (e.g., insulin, glucagon, adrenaline, gastrin, TRH).
- Focus on each hormone's role in maintaining homeostasis, metabolism, and stress response.
Cardiac Conduction System Anatomy and Function
- Familiarize yourself with the heart's electrical conduction system (SA node, AV node, Bundle of His, Purkinje fibers).
- Understand the "natural pacemaker" role.
- Examine the functional advantages of red blood cell shapes and features, including surface area for oxygen transport.
Blood Vessels and Circulation
- Learn to distinguish arteries and veins based on structural characteristics (e.g., presence of valves, depth in body) and functions (e.g., blood flow direction).
- Review terms like "aorta," "vena cava," and oxygenation status.
Nervous System Components and Cell Types
- Identify key neuron parts (dendrites, soma, nucleus, myelin sheath).
- Understand their roles in signal transmission.
- Understand the support roles of glial cells versus neurons, including insulation and protection.
- Differentiate between chemical and electrical synapses.
- Review the concept of an action potential in signal propagation.
Heart Anatomy: Valves and Chambers
- Recognize key heart structures, including the mitral and tricuspid valves, and the right and left atria and ventricles.
Red Blood Cells (Erythrocytes)
- Review red blood cell shape, function, and classification.
Skeletal System and Bone Structure
- Know the difference between red and yellow marrow locations, and types of bones (long, flat, irregular).
Endocrine Glands in Context
- Be familiar with endocrine glands' locations and their relationships to other organs, especially adrenal glands and kidneys.
Homeostasis and Skin Functions
- Understand homeostasis and the skin's functions, including vitamin D synthesis, thermoregulation, and dehydration prevention.
Cellular Components and Functions
- Review the structure and function of key organelles (mitochondria, endoplasmic reticulum, plasma membrane).
Tissues and Anatomical Planes
- Differentiate muscle, nervous, epithelial, and connective tissues.
- Recognize sagittal, coronal, and transverse planes for anatomical orientation.
Body Quadrants and Cavities
- Identify locations of major body cavities (cranial, thoracic, abdominal, vertebral) and body quadrants for abdominal regions.
