ventral | relating to the belly or abdomen |
volar | relating to palm of the hand or the sole of the foot |
plantar | relating to the sole or undersurface of the foot |
axial (3 parts) | cephalic (head), cervical (neck), trunk |
appendicular | upper limbs, lower limbs |
sagittal plane | divides body into left and right halves |
frontal plane | divides the body into front and back halves |
transverse plane | divides body into top and bottom half |
coronal axis | runs mediolateral, 90 degree angle with the sagittal plane, same orientation as frontal plane |
anteroposterior axis | same orientation as the sagittal plane, runs front to back |
What movements use the coronal axis? | flexion/extension |
What movements use the anteroposterior axis? | abduction/adduction |
vertical axis | runs down through the head, right angle to the transverse plane |
what movements use vertical axis? | internal/external rotation |
How many bones in the human body? | 206 |
How many bones in the axial skeleton versus the appendicular skeleton? | 80 axial bones, 126 appendicular bones |
What are the 5 functions of the skeleton? | 1. Protection of the heart, lungs, organs 2. Support to maintain posture 3. Movement by serving as points of attachment for muscles 4. mineral storage (calcium/phosphorus) 5. hemopoiesis - process of blood cell formation in red blood marrow |
What are the 5 types of bones? | long, short, flat, irregular, sesamoid |
what type of bone contains the medullary canal? | long bones ex. phalanges, metacarpals, tibia, fibula, femur, radius, ulna |
What bones are small and cubical shaped? | Short bones ex. carpals and tarsals |
Which bones usually have a curved surface? | flat bones ex. sternum, scapula |
What are examples of irregular bones | entire spine, pubis, and maxilla |
Which bones are small bones embedded in the tendons and provide protection as well as mechanical advantage? | sesamoid bones ex. patella |
Diaphysis | long cylindrical shaft of bone |
cortex | hard, dense, compact bone that forms walls of diaphysis |
Periosteum | dense, fibrous membrane covering outer surface of diaphysis |
endosteum | fibrous membrane that lines the inside of the cortex |
medullary cavity | b/w walls of diaphysis, contains yellow or fatty marrow |
epiphysis | ends of long bones formed from spongy bone |
epiphyseal plate | growth plate - thin plate of cartilage that separates diaphysis and epiphyses |
articular cartilage | covers the epiphysis to provide cushioning and reduce friction |
endochondral bones | bones which develop from hyaline cartilage; grow rapdily into the structures shaped similarly to the bones they will become |
when does longitudinal growth stop? | when the epiphyseal plates disappear and close |
osteoblasts | from new bone |
osteoclasts | "clean up crew" - break down/resorb old bones |
What is the breakdown of bone weight | 60-70% bone weight - calcium carbonate and calcium phosphate 25-30% water |
What is the point of collagen? | provides some flexibility and strength in resisting tension |
What causes progressive loss of collagen & increases brittleness? | aging |
What is most outer bone made up of? | cortical bone |
Which type of bone has higher porosity? | cancellous/spongy |
Bones reshape themselves based upon what? | stresses placed upon them |
bone mass increases over time with what? | increased stress |
Which type of bone is stifffer? Which type can withstand more strain? | Cortical is stiffer, but Cancellous can undergo greater strength |
What are the two main types of bone markings? | Processes and Cavities |
Articulation | connection of bones at a joint usually to allow movement between the surfaces of the bones |
What are the 3 major classifications of joints? | Synarthrodial, Amphiarthrodial, Diarthrodial |
synarthrodial joint | immovable joint (ex. skull sutures) |
syndesmosis | two bones joined together by a strong ligament or an interosseus membrane that allows minimal movement between the bones ex. tibiofibular joint |
ampiarthrodial joint | slightly moveable (syndesmosis, synchonrosis, symphsis) |
synchrondosis | joint separated by hyaline cartilage that allows slight movement between the bones (ribs) |
symphysis | joint separated by a fibrocartilage pad that allows slight movement (pelvis) |
diarthrodial joints | synovial joints; freely moveable, composed of a sleevelike joint capsule (cartilage) and secretes synovial fluid to lubricate the joint cavity |
how many planes of motion do diarthrodial joints have motion in | 1 or more |
arthrodial joints | gliding joints; consist of 2 plane or flat bony surfaces which butt against each other, little motion possible (ex. spine, intercarpal joints) |
ginglymus joint | hinge joint; uniaxial articulation. only motion in one plane (ex. knee, elbow) |
trochoid joint | pivot joint; uniaxial proximal and distal rasial-ulnar joints |
condyloid joint | knuckle joint; ball and socket 2nd-5th metacarpals |
enarthrodial joint | multiaxial/triaxial ball and socket joint ex. hip/shoulder |
motions of the enarthrodial joints | flexion, extension, abduction, adduction, diagonal abduction & adduction, rotation, (circumduction) |
motions of the condyloid joint | flexion, extension, abduction & adduction (circumduction) |
motions of the arthrodial joint | flexion, extension, abduction, adduction, diagonal abduction & adduction, & rotation, (circumduction) |
sellar joint **** | saddle joint; triaxial joint, two repciprically concave and convex articular surfaces |
motions of the sellar joint | Flexion, extension, adduction & abduction, circumduction & slight rotation |
physiological movements | flexion, extension, abduction, adduction & rotation occur by bones moving through planes of motion about an axis of rotation at a joint |
accessory motions | spin, glide, & roll |
spin | a single point on one articular surface rotates about a single point on another point on another articular surface |
roll | a series of points on one articular surface contacts with a series of points on another articular surface |
glide | slide; a specific point on one articulating surface comes in contact with a series of points on another surface |
can physiological motion occur if accessory motion is prevented? | no, unless by joint compression or distraction |
which two motions must occur together to some extent? | glide and roll |
