Intro To Anatomy Flashcards
Gross anatomy
Study of large structures without the aid of a microscope
Microanatomy
Study of small structures with the aid of a microscope
Surface anatomy
Study of body surface features
Medical anatomy
Study of structures changed by disease
Cytology
Study of cells
Histology
Study of tissues
Systematic vs regional anatomy
Systematic is organized by systems and regional is organized by body regions
Four main types of tissues
Epithelial, connective, muscle, nervous
Organ level
Consists of two or more different types of tissues
System level
Consists of multiple organs that combine to form a very general task
The complete organism
Composed of 11 systems to maintain life
Integumentary system
Skin, protects underlying tissues and prevents fluid loss
Skeletal system
Bones, joints, supports and protects softer body parts, stores minerals and produces blood cells
Muscular system
Skeletal muscles, produces movement of bones at joints, generates heat
Nervous system
Brain, spinal cord, nerves, monitors changes in environment, interprets the changes, and initiates a response
Endocrine system
Pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, thymus, alters the activity of cells by release of hormones
Cardiovascular system
Heart, blood vessels, transports blood throughout all areas of the body
Lymphatic system
Spleen, thymus, tonsils, lymph nodes, lymphatic vessels, protects the body from foreign particles and cells
Respiratory system
Nose, pharynx, larynx, trachea, bronchi, lungs, exchanges gases between the bloodstream and the external environment
Digestive system
Simplifies food particles into their basic nutrient subunits for absorption into the bloodstream
Urinary system
Forms urine to maintain water and salt balance, pH, and nitrogenous waste levels in the blood
Reproductive systems
Produces gametes to undergo fertilization for the creation of new individuals
Metabolism
How the body obtains and uses energy
Catabolism
The breakdown of molecules to produce energy
Anabolism
The use of energy to power all activities, such as building new molecules
Directional terminology
Refers to a set of terms used to describe the location of structures
