Study Notes

Anatomical Terms

Superior and Inferior: Indicate relative position toward (superior) or away (inferior) from the head.
Examples of superior: eyes superior to the nose; nose superior to the mouth.
Examples of inferior: mouth inferior to the neck; neck inferior to the chest.
Anterior and Posterior: Refer to positions in relation to the front (anterior) or back (posterior) of the body.
Anterior: ventral, front side; example: abdominal muscles are anterior to the spine.
Posterior: dorsal, back side; example: spine is posterior to the abdominal muscles.

Proximal and Distal

Relate to the attachment point or origin of structures, such as limbs.
Proximal: closer to the trunk or attachment point.
Distal: farther from the trunk or attachment point.

Superficial and Deep

Superficial: Nearest to the body’s surface; implies focusing on external appearance.
Deep: Away from the body's surface; penetrates far below the skin's surface, such as in deep wounds.

Cell Level

Cells are basic structural and functional units composed of organelles.
Nucleus contains hereditary information; mitochondria produce adenosine triphosphate (ATP).
Understanding cellular characteristics is essential for understanding anatomy and physiology.

Tissue Level

Tissue consists of similar cells and surrounding materials, determining tissue function.
Four basic tissue types:
- Epithelial
- Connective
- Muscle
- Nervous

Organ Level

Organs consist of two or more tissue types performing common functions.

Characteristics of Life

Essential Characteristics:
- Organization: Interrelationships among parts of an organism.
- Metabolism: All chemical reactions in an organism, including energy conversion and synthesis.
- Responsiveness: Ability to react to stimuli.
- Growth: Increase in size or mass.
- Development: Differentiation from a generic to a specialized state.
- Reproduction: Ability to produce new individuals.

Metabolism

Encompasses biochemical reactions for energy and synthesis, utilizing raw materials.
Includes catabolism (breaking down substances) and anabolism (building up substances).
Development entails growth and specialization of cells following fertilization.

Review Questions

Q1: Physiology relates to functions of living things, whereas anatomy pertains to structures.
Q8 and Q9: Metabolism is defined as the totality of chemical reactions occurring in an organism.
