Study Notes

The Human Body: An Orientation

The human body is composed of cells, organs, and systems that work together to maintain life.
There are two main fields of study: anatomy (structure) and physiology (function).

Anatomy Levels of Study

Gross anatomy: study of large, easily observable structures
Microscopic anatomy: study of structures that cannot be seen with the naked eye (cells, tissues, molecules)

Organ System Overview

Integumentary system: forms the external body covering, protects deeper tissue from injury, regulates body temperature, and synthesizes vitamin D
Skeletal system: protects and supports body organs, provides muscle attachment for movement, and produces blood cells
Muscular system: produces movement, maintains posture, and produces heat
Nervous system: fast-acting control system that responds to internal and external changes, activates muscles and glands, and sends signals to the brain
Endocrine system: secretes regulatory hormones that control growth, reproduction, and metabolism
Urinary system: eliminates nitrogenous wastes and maintains acid-base balance
Reproductive system: produces offspring
Lymphatic system: picks up fluid leaked from blood vessels, cleanses the blood, and disposes of debris
Respiratory system: supplies oxygen and removes carbon dioxide through gaseous exchange
Digestive system: breaks down food into absorbable units, allows for nutrient absorption

Necessary Life Functions

Maintain boundaries
Move
Respond to stimuli
Digest and absorb nutrients
Excrete wastes
Grow and reproduce

Homeostasis

Maintenance of a stable internal environment
Dynamic state of equilibrium
Necessary for normal body functioning and to sustain life

Language of Anatomy

Special terminology is used to prevent misunderstanding
Exact terms are used to describe position, direction, and regions

Body Planes and Sections

Three planes of space: sagittal, frontal, and transverse
Body sections: sagittal (divides into left and right parts), frontal (divides into anterior and posterior parts), and transverse (divides into superior and inferior parts)

Directional Terms

Superior (cephalad): toward the head end or upper part of a structure
Inferior (caudal): away from the head end or toward the lower part of a structure
Ventral (anterior): toward the front of the body
Dorsal (posterior): toward the backside of the body
Medial: toward the midline of the body
Lateral: away from the midline of the body
Proximal: close to the origin of a body part or point of attachment to a limb
Distal: farther from the origin of a body part or point of attachment to a limb

Regional Terms

List of regional terms: abdominal, cephalic, ocular, auricular, buccal, nasal, oral, axillary, cubital, carpal, palmar, thoracic, umbilical, lumbar, inguinal, pubic, gluteal, patellar, popliteal, crural, sural, tarsal

Body Cavities and Regions

List of body cavities and regions:
- Abdominal quadrants: right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac
- Thoracic regions: cephalic, ocular, auricular
- Other regions: nasal, oral, axillary, cubital, carpal, palmar, thoracic, umbilical, lumbar, inguinal, pubic, gluteal, patellar, popliteal, crural, sural, tarsal
