Chapter 1 - Intro Structural Units Flashcards
Anatomy
Shape and structure of an organism’s body and the relationship of one body part to another.
Physiology
Function of each body part and how the functions of various body parts coordinate to form a complete living organism.
Branches of Anatomy
- Gross Anatomy
- Microscopic Anatomy
- Developmental Anatomy
- Comparative Anatomy
- Systematic Anatomy

Midsagittal Plane
Midline
- imaginary line straight down middle of body, diving body into left & right sections.
Sagittal Plane
Divides body into right and left parts
Coronal Plane
AKA: Frontal Plane
- Vertical Plane, dividing body into front & back sections.
Transverse Plane or cross section
Horizontal plane, divides body into upper and lower sections.
Posterior (Dorsal) cavity
Includes cranial cavity and spinal cavity.
Cranial cavity
Brain
Spinal cavity
Spinal cord
Anterior (Ventral) cavity
Includes Thoracic cavity and abdominopelvic cavity. Regions of the thorax and pelvis.
Epigastric region (upper)
Just below sternum. Part of Abdominopelvic or Abdominal Region.
Hypochondriac regions
Left and right regions, just below the ribs. Part of Abdominopelvic Regions.
Umbilical (middle)
Located around the navel. Part of Abdominopelvic Regions.
Right & Left Lumbar
Extend from anterior to posterior. Part of Abdominopelvic Regions.
Hypogastric (lower)
Pubic area. Part of Abdominopelvic Regions.
Right and Left Iliac
AKA: right and left inguinal areas. Part of Abdominopelvic Regions.
Orbital Cavity
Includes eyes, eyeball muscles, optic nerves, and lacrimal (tear) ducts.
Nasal cavity
Parts forming the nose.
Oral/Buccal Cavity
Teeth and tongue.
Living Organisms
May be one-celled or multi-celled; include humans, plants, animals. All are capable of carrying on life functions that allow living organisms to live, grow, and maintain themselves.

Homeostasis
Ability of the body to regulate its internal environment within narrow limits. Essential to survival. Works on a negative feedback system.
Metabolism
Functional activities of the cell that result in growth, repair, energy release, use of food, and secretions.
Anabolism
Building up
Catabolism
Breaking down.
Metric System
- Measurements for length, weight, and volume.
- A decimal system.
- Based on the power of ten.
- Uses prefixes such as centi-, milli-, and micro-.
- Lengths measured in meters.
- Weights measured in grams.
- Volumes measured in liters.
