chapter 1: a first look at anatomy Flashcards
the study of structure
anatomy
the scientific discipline that studies the functions of body structures
physiology
examines structures that cannot be viewed by the unaided eye
microscopic anatomy
investigates the structure and relationships of large body parts that are visible to the unaided eye
gross anatomy // macroscopic anatomy
study of single body cells and their internal structures
cytology
the study of tissues
histology
examines the similarities and differences in the anatomy of different species
comparative anatomy
investigates the changes in structure within an individual from conception thru maturity
developmental anatomy
concerned specifically w developmental changes prior to birth
embryology
examines all the structures in a particular region in the body as one complete unit
regional anatomy
examines both superficial anatomic markings and internal body structures as they relate to the skin covering them
surface anatomy
studies gross anatomy of each system in the body
systemic anatomy
examines all anatomic change resulting from disease
pathologic anatomy
studies the relationships among internal structures that may be visualized by specific medical imaging procedures
radiographic anatomy
investigates the anatomic landmarks used before and after surgery
surgical anatomy
simplest level that involves atoms and molecules
chemical level
the smallest units of matter
atoms
when 2 or more atoms combine they form a ____
molecule
serve as basic units of structure and function in organisms
cells
level in which similar cells w common function form
tissue level
precise organizations of similar cells that perform specialized functions
tissues
different tissue types combine to form an organ at this level
organ level
level that consists of related organs that work together
organ system level
highest level of structural organization in the body
organismal level
a regulatory system that controls body movement, responds to sensory stimuli, and helps control all other systems of the body
nervous system
consists of the glands and cell clusters that secrete hormones, some of which regulate body and cellular growth, chem levels in the body, and reproductive functions
endocrine system
consists of the heart, blood, and blood vessels
cardiovascular system
transports and filters lymph and initiates an immune response when necessary
lymphatic system
responsible for exchange of gases between blood and air in lungs
respiratory system
mechanically and chemically digests food materials, absorbs nutrients, and expels waste products
digestive system
filters the blood and removes waste products from the blood, concentrates waste products in the form of urine, expels urine from the body
urinary system
produces male sex cells and male hormones, transfers sperm to female
male reproductive system
produces female sex cells and female hormones, receives sperm from male, site of fertilization of oocyte, site of growth and development of embryo and fetus
female reproductive system
organization, metabolism, growth/development, responsiveness, adaptation, regulation, reproduction
characteristics common to all organisms
provides protection, regulates body temp, site of cutaneous receptors, synthesizes vit D, prevents water loss
integumentary system
provides support and protection, site of hemopoiesis, stores calcium and phosphorus, provides sites for muscle attachments
skeletal system
produces body movement, generates heat when muscles contract
muscular system
position where individual stands upright w feet parallel and flat on floor
anatomical position
vertical plane that divides the body into anterior (front) and posterior (back) parts
coronal plane
cuts perpendicularly along long axis of body or organ
transverse plane / cross sectional plane / horizontal plane
extends through body or organ vertically and divides the structure into right and left halves
midsagittal plane / median plane
plane that is parallel to midsagittal plane but either to the left or right
sagittal plane
in front of; toward front surface
anterior
in back of; toward back surface
posterior
at back side of human body
dorsal
at belly side of human body
ventral
