Anatomy & Physiology I

This set of flashcards covers key terms and concepts related to Anatomy & Physiology I, including definitions of important terms, types of tissues, body cavities, anatomical planes, and physiological functions.

Anatomy

The study of the body structures and their relationships.

Physiology

The study of the function of body organs.

Histology

The study of the microscopic anatomy of cells and tissues.

Pathology

The study of diseases affecting the body.

Homeostasis

The condition of equilibrium in the body’s internal environment.

Epithelial Tissue

Covers exterior surfaces, lines cavities, and forms glands.

Connective Tissue

Binds cells and organs of the body together, providing support and protection.

Muscle Tissue

Tissue that contracts to produce movement.

Nervous Tissue

Allows propagation of electrochemical signals between different body regions.

Dorsal Body Cavity

Contains the cranial and vertebral cavities.

Ventral Body Cavity

Contains the thoracic and abdominopelvic cavities.

Abdominal Regions

Nine regions that describe the anatomy of the abdominal area.

Proximal

Refers to a structure closer to the trunk or point of origin.

Distal

Refers to a structure further from the trunk or point of origin.

Medial

Closer to the midline of the body.

Lateral

Further from the midline of the body.

Superior

A structure closer to the head.

Inferior

A structure closer to the feet.

Sagittal Plane

Divides the body into right and left sides.

Coronal Plane

Divides the body into anterior and posterior sections.

Transverse Plane

Divides the body into upper and lower halves.

Metabolism

The sum of anabolic and catabolic reactions within the body.

Anabolism

The process of combining molecules to form complex substances.

Catabolism

The process of breaking down large molecules for energy.

Feedback Systems

Cycles of events that monitor and adjust physiological values.
