KINE 3050: Bone & Joint Components

condyle

rounded projection that articulates w/ another bone

epicondyle

A rounded projection at the end of long bones but lateral to axis and not necessarily articulation part

facet

small, smooth & usually flat articular surface

foramen

hole, usually for nerve or vessels to pass through

fossa

hollow depression or pit

fovea

smaller hollow depression or pit

head

spherical articular end of a long bone

line (bone)

raised line or small ridge

neck

part of bone that joins the head to the shaft

notch

indentation on the border or edge of a bone

process

projecting part of a bone

spine

sharp projecting part of bone

trochanter

large, knobby projection

tubercle

small, knobby projection

tuberosity

knobby projection

gliding joint, intercarpal, intertarsal, acromioclavicular

allows one bone to slide over another

What are 3 examples? (wrist, ankle, shoulder girdle)

hinge joint, humeroulnar, tibiofemoral, talotibial, talofibular, interphalangeal

uniaxial joints that allow only ONE degree of freedom of movement; ginglymus joints

What are 5 examples (elbow, knee, 2 ankle, finger & toe)

pivot joint, radioulnar, atlantoaxial

Allows for rotation around the length of a bone, and only allows for rotation.

What are 2 examples (forearm & 1st/2nd vertebrae)

ellipsoid joint, radiocarpal, metacarpophalangeal, metatarsophalangeal, occipitoatlantal

has two types of movement but allows opposition movement only to a small degree; also called ovoid joints

What are 4 examples: wrist, fingers, toes, head & neck

saddle joints, carpometacarpal

biaxial joints that allow 2 degrees of freedom

What is 1 example: thumb

flexion & extension

What movements do hinge joints allow?

rotation

What movements do pivot joints allow?

flexion, extension, abduction, adduction, circumduction

What movements do ellipsoidal & saddle joints allow?

ball-and-socket joint, glenohumeral, hip, sternoclavicular

Triaxial that are the most freely moveable of the synovial joints?

What are 3 examples: shoulder, hip, shoulder girdle & axial skeleton
