Anatomy
The study of the structure of the body and its parts
Physiology
The study of how the body parts function
Regional Anatomy
analysis of specific parts of the body
Gross Anatomy
the study of parts of the body that can be seen
Microscopic Anatomy
study of structures that must be seen through a microscope
Embryology
the study of the development of a body from conception through the first eight weeks
comparative anatomy
anatomy of nonhuman species used to assist in the study of the human body
systemic anatomy
study of organ systems and their related functions
Organ System
A group of organs that work together to perform a specific funtion
Skeletal System
bones and their associated cartilage, joining and ligaments
digestive system
mouth, esophagus, stomach, etc. allows the body to break down and absorb nutrients and eliminate waste
integumentary system
skin, hair, nails, sweat glands, and protects the body, regulates body temp, prevents water loss, and produce Vit D
Endocrine system
made up of glands and organs that secrete hormones to regulate body processes
Muscular System
muscles, allows the body to move and maintain posture, and internal organs to function
organ
a group of tissues specialized for a particular function
tissues
groups of cells forming various building blocks of life
nervous tissue
ability to conduct electrical signals
connective tissues
bone, cartilage, deeper layer of skin between organs
epithelial tissue
outer layer of tissues that aid in protection, like skin
cells
the basic unit of life
organelles
little organs
homeostasis
a state of dynamic equilibrium in the body with respect to its internal environment and its funtions
set point
the ideal normal value of a variable, determines the set point and signals a response to correct imbalances
stress
a factor that causes one or more physiological variables to move away from its homeostatic point
effector
a structure in the body that can change the value of a variable in response to a signal from the control center
control center
the part of the body, either central nervous system or endocrine gland, that receives info about a variable, determines the set point and corrects imbalances.
negative feedback mechanism
a control mechanism consisting of receptors, control center, and effectors through which homeostasis in the body is maintained by regulation of the body's organ systems
