These bones have complex shapes and cannot fall into any of the other classifications of bones.
What are Irregular Bones (coccyx, temporal, maxilla, vertebrae, calcaneus)
100
This type of joint is Bi-axial and have saddle shaped surfaces fitted into each other. Allows flexion, extension, abduction, adduction, and circumdunction. Found in the carpometacarpal joint of the thumb.
What is Saddle Joint
100
This bone is the longest and heaviest bone in the body.
What is the Femur
100
A depression or hollow
What is Fossa
100
This is the lubricating fluid whose function is to prevent friction at the joints
What is Synovial Fluid
200
There are approximately this many bones in an adult body.
What is 206/214
200
This type of joint is Poly-axial. It allows flexion, extension, abduction, adduction, true circumduction, and rotation on long axis.
What is Ball & Socket ( Found in the Hip and Shoulder joints)
200
Which skeleton classification has 80 bones.
What is Axial Skeleton
200
A large process for muscle attachment
What is Trochanter
200
Joints are classified according to the amount of motion they permit. This type of joint is FREELY movable like the hip and thumb.
What is Diarthrotic
300
This type of bone is found in extremities and consist of a body or shaft. They are not straight, but curved.
What are Long Bones (clavicle, humerus, radius, tibia, fibula, phalanges)
300
This type of joint allows gliding or twisting and is Uni-axial.
What are Gliding Joints found in the intercarpal/tarsal joints, vertebrae zygapophyseal joint)
300
This is the bony landmark that we sit on!
What is Ischial tuberosity
300
A small rounded process
What is Tubercle
300
The purpose of this is to cushion the bones at the joints, prevent jarring between bones in motion, and to give shape to eternal features such as the nose and ears.
What is Cartilage
400
These type of bones are free floating that develop in certain tendons where there is increased friction around a joint.
What are Sesamoid Bones (patella and sesamoid bones of the foot and hand)
400
This type of joint is found in the elbow. It is Uni-axial and has a concave surface that glides around a convex surface allowing flexion and extension.
What is Hinge Joint
400
This is the enlarged area on the ends of long bones that articulates with other bones.
What is Epiphysis
400
a rounded knuckle like prominence, usually at a point of articulation.
What is condyle
400
This type of fracture is when the bone pokes through the skin.
What is compound/open
500
The skull and scapula are considered this type of bone.
What are Flat Bones.
500
This type of joint is Bi-Axial. It permits flexion, extension, adduction, abduction and cirumcduction in the wrist and 2nd-5th metacarpophalangeal joints.
What is Condyloid (ellipsoid) joint
500
This kind of bone is SPONGY and is the inner part of the bone.
What is Cancellous
500
a large rounded process
What is tuberosity
500
This is a chronic disease that erodes the articular cartilage and results in abnormal bone thickening and progressive joint immobility.
