Study Notes

Anatomy and Physiology

Anatomy: The study of the normal structure of the body.
Physiology: The study of the functions of the body and its parts.

Types of Anatomy

Gross Anatomy: Structures visible to the naked eye.
Surface Anatomy: External form and marking of internal structures.
Systemic Anatomy: Studies the body system by system.
Regional Anatomy: Focuses on specific body regions (e.g., head, chest).
Anatomical Imaging: Techniques like x-rays and MRIs used to visualize internal structures.

Levels of Organization

Chemical Level: Atoms combine to form molecules.
Cell Level: The basic structural and functional unit of living organisms.
Tissue Level: Groups of similar cells working together to perform specific functions.
Organ Level: Two or more types of tissues that perform specific functions together.
Organ System Level: A group of organs working towards a common purpose.
Organism Level: A complete living entity.

Characteristics of Life

Development: Changes over time in an organism.
Reproduction: Formation of new cells or organisms.
Metabolism: Energy use for growth, movement, and maintenance.
Responsiveness: Ability to sense and respond to environmental changes.
Growth: Increase in size or substance, involving cell number or size.

Major Body Systems

Integumentary System: Protects, regulates temperature, and prevents water loss; includes skin, hair, nails.
Skeletal System: Provides protection, supports weight, facilitates movement; includes bones and associated tissues.
Muscular System: Produces movements, maintains posture, generates heat; includes all muscles attached to bone.
Nervous System: Controls sensations, movements, and intellectual functions; includes brain, spinal cord, nerves.
Endocrine System: Regulates functions through hormones, influencing metabolism and growth; includes various endocrine glands.
Cardiovascular System: Transports nutrients and waste across the body; includes heart and blood vessels.
Lymphatic System: Removes foreign substances, combats disease, maintains fluid balance; includes lymph vessels and nodes.
Respiratory System: Exchanges oxygen and carbon dioxide; includes lungs and passages.
Digestive System: Processes food, absorbs nutrients; includes mouth, stomach, intestines.
Urinary System: Removes waste from blood, regulates pH and electrolyte balance; includes kidneys and bladder.
Reproductive System: Produces gametes and hormones; varies between males (testes) and females (ovaries).

Anatomical Terms and Positions

Inferior (caudal): Away from the head.

Midline: Divides the body into right and left halves.

Body Cavities

Ventral Cavity: Contains thoracic and abdominopelvic cavities.
Thoracic Cavity: Houses lungs and heart.
Mediastinum: Area between lungs containing the heart and major blood vessels.
Abdominopelvic Cavity: Contains abdominal (digestive organs) and pelvic (urinary and reproductive organs) cavities.
Serous Membrane: Lining of closed body cavities, separating organs with serous fluid.

Epigastric Region: Contains liver, stomach, and pancreas.
Left Hypochondriac Region: Houses stomach, spleen, and parts of intestines.
Right Lumbar Region: Comprises ascending colon and right kidney.
Umbilical Region: Contains duodenum and small intestine.
Left Lumbar Region: Houses descending colon and left kidney.
Right Iliac Region: Contains appendix and cecum.
Hypogastric Region: Includes bladder and reproductive organs.

Planes of the Body

Sagittal Plane: Divides the body into left and right sections.
Midsagittal Plane: Splits the body into equal left and right halves.
Parasagittal Plane: Divides the body into unequal left and right portions.
Transverse Plane: Divides the body into superior (upper) and inferior (lower) parts.
Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) parts.

Section Types

Longitudinal Section: Cut along the long axis of an organ.
Transverse Section: Cut completely through an organ.
Oblique Section: Cuts made at an angle.

Medical Conditions

Pericarditis: Inflammation of the pericardium.
Pleurisy: Inflammation of the pleura.
Peritonitis: Inflammation of the peritoneum.
Appendicitis: Inflammation of the appendix.

Retroperitoneal Structures

Organs located behind the peritoneum include kidneys, adrenal glands, part of the pancreas, and urinary bladder.
Mesenteries: Two layers of peritoneum fused to provide pathways for nerves and blood vessels to digestive organs.
