The Human Body Flashcards
(62 cards)
Anatomy
A study that focuses on the physical structure of the body and its systems
Physiology
Goes a step further, examining the standard functions and activities of these biological components
Pathophysiology
The study of functional changes that accompany a particular disease or syndrome
Topographic Anatomy
The superficial landmarks of the body that serve as guides to the structures that lie beneath them
Anatomic Position
The position of reference is where the patient stands facing forward, arms at the side, and palms facing forward.
Anatomic Planes
Imaginary straight line divisions begin with 3 main axes
Coronal (frontal) Plane
tuns vertically through the body and divides the front and back from left to right
Sagittal (lateral) Plane
Runs vertically, but divides the body into left and right sections head to toe
Midsagittal (midline) Plane
Divides the body equally into left and right halves
Ex. Nose to the umbilicus are found along the midline
Transverse (axial) Plane
Divides the body horizontally into top and bottom sections waste
Skeletal System
- Provides a Structural framework to bear the body’s weight
- Establish a framework to attach soft tissues and internal organs
3 protect vital organs such as the heart and lungs.
4 Red marrow within the internal cavities of many bones produces RBCs
Axial skeletons
Forms the longitudinal axis of the body, from the skull to the tailbone ( coccyx)
Coccyx
Tailbone or the last 3 or 4 vertebrae of the spine; the tailbone
Thoracic Cage
The chest or rib cage
Appendicular Skeleton
The portion of the skeletal system that comprises the arms, legs, pelvis, by which they connect with the axial skeleton, for example, the shoulder
The pelvis
Includes portions from the axial and appendicular skeletons
Joint
Where two bones meet
How are joints named?
Formulated by combining the names of these adjoining bones
For example, the sternoclavicular joint- the sternum and the clavicle
Ligaments
Fibrous tissues that connect bone to bone, helping stabilize these joints.
Cartilage
Semirigid yet flexible tissue that covers and cushions the ends of articulating bones
Tendons
The tissues that attach bone to muscle
Symphyses
Joints that have grown together to form a very stable connection
Joint Capsule
The bone ends of a joint are held together by a fibrous sac.
Sac is composed of connective tissue (connecting bone to bone)
Certain points around the joint are lax and thin, permitting movement.
In other areas, it is thick and resists stretching and bending shoulder having fewer ligaments, is free to move in almost any direction
Ex sacroiliac joint is virtually surrounded by tough, thick ligaments and will therefore have little ROM.
Sacroiliac Joint
The connection point between the pelvis and the vertebral column
