Anatomy
physical structure of body and systems
Physiology
normal functions and activities of body parts/systems
Pathophysiology
functional changes of body parts when diseased
Topographic Anatomy
surface structures
Umbilicus
belly button
Anatomic Position
patient palms and feet facing you
Coronal/Frontal Plane
vertical, front and back sections
Sagittal/Lateral Plane
vertical, left and right sections
Midsagittal/Midline Plane
equal left and right sections
Transverse/Axial Plane
horizontal, top and bottom sections
Skeletal System
structural support, attachment for tissues, protect vital organs, red marrow produces RBC
Axial Skeleton
vertical from coccyx to skull, includes thoracic cage and vertebral column
Coccyx
5th section of vertebrae, 4, tailbone
Thoracic Cage
rib cage
Appendicular Skeleton
upper and lower limbs and where they attach to axial skeleton
Joint
where 2 bones meet, named after 2 adjoining bones, allows movement
Ligaments
fibrous tissue that connects and stabilizes joints
Cartilage
flexible tissue that cushions the ends of bones at joints
Tendon
connect muscle to bone
Symphyses
joint where only some motion is possible
Joint Capsule
sac at the ends of bones in joint, some parts thin for movement, some parts thick restrict movement
Sacroiliac Joint
joint surrounded by thick ligaments, allows little movement
Articular Cartilage
on ends of bones in moving joints, allows joint to glide
Synovial Membrane
inner lining of joint capsule, makes synovial fluid
Synovial fluid
lubricates joints, allows bones to glide in joints
Ball and Socket Joint
rotation and bending, ex. shoulder
Hinge Joint
only bending, ex. finger elbow and knee
Flexion
bending of joint
Extension
straightening of joint
Skull
28 bones, cranium, facial bones and ear bones
