KPE160 Module 2 Exam Questions And 100% Correct AnswersBones- Answer Act as rigid levers in the body-segment system.
Joints - Answer Link bones in the body-segment system.
How Can We Move?- Answer Use external loads by pushing on the world, which pushes
back on us, and generates propulsion. Reaction forces cause movement. (Law of Inertie
(1st Law))
How Can a Free Body Cause an External Force? - Answer Newton's Law of Reaction (3rd
Law) states that if you push or pull something it pushed or pulls back.
How Can We Push or Pull Something? - Answer By changing our shape! Rigid body can't
cause itself to move.
How Do We Change Shape? - Answer By moving our joints in the lined-segment system.
Due to bone levers as well. Muscles are the internal motors that control the joint
positions and motion in our linked-segment system (skeleton).
Linked-Segment System - Answer Skeleton and body.
Segmentation - Answer Pieces that are stuck together. Our body is naturally divided into
multiple segments around bones, which permits relative motion between segments.
Body Segments - Includes the one bone plus the soft tissues that support it. Useful
because a number of bone segments can be combined into one body segment. We use
hierarchy of segments.
Skeletal Joints - A point of connection between adjacent segments (bones) in the body.
, Long Bones - Answer Have one dimension significantly greater than other dimensions.
Found only in extremities. Variety of other shapes can be found in the skull, spine,
hands, and feet.
Physes - Answer Growth plates near ends of bones that ossify after puberty. Determine
names of parts of long bones.
Metaphyses - Answer The tapering part beside physes. Between epiphysis and
diaphysis.
Diaphysis - Answer The long shaft between metaphyses.
Epiphyses - Answer The articular ends outside physes.
Apophyses - Answer Outgrowths of bone at the sites of attachment of muscles, tendons,
or ligaments.
Segmental Axis - Answer Straight line between the centres of proximal and distal joints.
Articular Axes - Answer Axes of articular surfaces at proximal and distal joints.
Diaphyseal Angles/Curves - Answer Deviation/angles/curvature relative to the
segmental axis in coronal and sagittal planes. Axial plane twisting of diaphysis.
Articular Axis Angles - Answer Coronal and sagittal angles between segmental and
articular axes. Axial plane angle (twist) between proximal and distal articular axes of a
long bone.
Articulations Solution Contact points between bones. Motion is constrained. Bones
cannot translate relative to each other due to contact and reaction forces between
