Study Notes
Body Regions and Planes
- The sternal region is located superior to the umbilical region.
- The frontal (or coronal) plane divides the body into anterior and posterior parts.
Homeostasis
- Homeostatic imbalance can lead to disease.
- The two systems responsible for monitoring homeostasis are the nervous and endocrine systems.
- Positive feedback is not a component of homeostatic control mechanisms.
Body Organization
- Complexity of biological organization progresses from cell to tissue, organ, organ system, and ultimately to the organism.
- Tissues consist of groups of cells sharing a common structure and function.
Air Composition
- Oxygen comprises 20% of the air we breathe.
Body Cavities
- The cranial cavity is part of the dorsal body cavity, while the ventral body cavity includes the thoracic and abdominopelvic cavities.
- The spinal cord is not housed in the ventral body cavity.
- The pleural cavity specifically houses the lungs.
Organ Systems
- The respiratory system includes the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.
- The spleen is part of the lymphatic system.
- The skeletal system is responsible for producing blood cells.
Feedback Mechanisms
- An example of positive feedback is labor contractions stimulated by oxytocin.
- Negative feedback does not include processes like blood clotting in response to a blood vessel injury.
Life Functions
- Intelligence is not considered a necessary function for human life.
- Responsiveness is the ability to sense and respond to environmental changes.
Anatomical Terms
- The anatomical position is characterized by being erect, with feet forward, arms at the sides, palms facing forward, and head facing forward.
- The median or midsagittal plane divides the body into equal right and left regions.
Specific Body Structures
- The visceral pericardium directly covers the heart.
- The orbital cavity houses the eyes.
- The right lower quadrant (inguinal region) contains the cecum, appendix, right ovary and tube, right ureter, and right spermatic cord.
Metabolism
- Anabolism refers to metabolic processes that synthesize complex molecules from simpler ones.
- Serous fluid acts as a lubricant for organs, facilitating movement without friction.
- The synovial cavity is the space between articulating bones at most joints.
