Study Notes
Early Human Anatomy Study
- Early interest in the human body arose from concerns about injuries and illnesses.
- Observation of natural processes was crucial for understanding and treating sickness.
- Studying the human body helped ancestors identify causes of illness.
Key Definitions in Anatomy and Physiology
- Anatomy: The branch of science focusing on the morphology of body parts.
- Cell: The basic unit of function and structure in the human body.
- Metabolism: Encompasses all chemical reactions in an organism supporting life, including energy acquisition and utilization.
- Homeostasis: The body's ability to maintain a stable internal environment.
Body Structure and Organ Systems
- Axial Portion: Consists of the head, neck, and trunk.
- Mediastinum: Body cavity containing vital structures like the heart, esophagus, and trachea.
- Endocrine System: Includes glands such as the thyroid and pancreas.
- Cardiovascular System: Comprises the heart and blood vessels.
- Nervous System: Integrates and coordinates bodily functions and detects internal and external changes.
Aging and Physiological Changes
- First signs of aging typically noticeable in the third decade of life.
- Structural changes continue to occur in the body over time.
Anatomical Terminology
- Inferior: Refers to a position lower than another; example of positional relationship between mouth and nose when the body is inverted.
- Brachial Region: Refers to the upper arm area.
- Proximal and Distal: Terms used to describe positions relative to a point of reference; proximal means closer, while distal means further away.
- Lateral: Indicates a position on the outer side; for instance, the lungs are lateral to the heart.
Feedback Mechanisms in Physiology
- Negative Feedback Loop: A response that reverses a physiological change, exemplified by perspiration reducing body temperature during a race.
- Positive Feedback Loop: Involves self-amplifying cycles; for example, estrogen in a feedback loop with the hypothalamus and anterior pituitary.
Hormonal Regulation
- Estrogen: Hormone involved in positive feedback mechanisms between the ovary and anterior pituitary.
- Luteinizing Hormone: Released by the anterior pituitary, part of the positive feedback loop with ovaries.
- Progesterone: Released after ovulation, causing a negative feedback effect on the hypothalamus and anterior pituitary.
Serous Membrane
- Parietal Peritoneum: Lines the abdominal cavity.
- Visceral Peritoneum: Covers the surface of the abdominopelvic organs.
Intracellular Components
- Organelles: Structures within cells that perform specific functions.
- Intracellular Fluid: The solution present within cells that supports organelle activity.
Thoracic Cavity
- The region between the lungs is known as the mediastinum, housing critical structures for bodily function.
