Term
Articulation
Definition
The junction of two or more bones
Term
Biomechanics
Definition
Determining the assumptions necessary (with appropriate justifications) so that the principles of mechanics may be applied to living systems.
Term
Describe the Anatomical Position
Definition
Palms forward, feet shoulder width apart, standing, feet directed forward, head parallel to floor.
Term
What are the three cardinal planes?
Definition
Sagittal, Frontal/Coronal, transverse/horizontal plane
Term
Medial
Definition
Close to the midline of the body; i.e. the belly button is Medial to the fingers
Term
Lateral
Definition
Away from the midline of the body i.e. the fingers are lateral to the belly button.
Term
Proximal
Definition
Closer to origin of a point of attachment; i.e. the elbow is proximal to the wrist
Term
distal
Definition
Further from the origin of a point of attachment; i.e. the wrist is distal to the elbow
Term
Posterior
Definition
Away from the front of humans; i.e. the triceps are posterior to the biceps.
Term
Anterior
Definition
Towards the front of the body in humans; i.e. the sternum is anterior to the spine.
Term
ventral
Definition
Towards the front of the body in humans; i.e. the sternum is ventral to the spine.
Term
dorsal
Definition
Away from the front of humans; i.e. the triceps are dorsal to the biceps.
Term
Superior
Definition
Towards top in humans; i.e. the skull is superior of the tarsals.
Term
Inferior
Definition
Towards the bottom of humans; i.e. the patella is inferior of the hip.
Term
Cranial
Definition
Towards the head in animals
Term
Caudal
Definition
Towards the bottom of animals
Term

Bending at a joint os that the angle becomes smaller
Term
Extension
Definition
Bending at a joint so that the angle becomes larger.
Term
abduction

Term
Name some actions performed in the Transverse plane.
Definition
i.e. twirling, spinning
Term
Name some actions performed in the frontal/coronal plane.
Definition
i.e. jumping jacks, side steps
Term
What are the three classifications of joints?
Definition
Fibrous, catilaginous, and synovial
Term
What are the nine basic features of a synovial joint
Definition
1. Articular Cartilidge 2. Ligaments 3. Tendons 4. Muscle 5. Synovial Membrane 6. Synovial Fluid 7.Bones
8. Fibrous capsule 9. Joint cavity
Term
What is the "Classic Trade-Off" of joints?
Definition
Increase flexibility, decrease stability
Term
Synarthrodial/Fibrous Joint
Definition
Bones of the joint are tightly bound together. No relative motion; i.e. the skull
Term
Pmphiarthrodial/cartilaginous joint
Definition
Bones are held together by either hyaline cartilage or byfibrocartilage. Limited motion; i.e. ribs
Term
Diarthrodial/synotial joints
Definition
Bones seperate by a lubricating fluid and cartilage. Relatively large range of motion; i.e. hip, shoulder
Term
What are the six types of synovial joints?
Definition
Gliding, Hinge, Pivot, Ellipsoid, Saddle, Ball and Socket
Term
What causes bone properties to vary?
Definition
Age, nutrition, use, genetics, gender, location on the body
Term
