Kinesiology Intro

Chapters 1 & 2

TermDefinition
What are the 2 types of Kinematics Osteokinematics and Arthokinematics
3 Planes of Motion with their Axis of Rotation 1. Saggital Plane (Frontal Axis) 2. Coronal Plane (Saggital Axis) 3. Transverse Plane (Vertical Axis
Distal fixed, Proximal moves (eg. Squats and Pull Ups) Closed Kinetic Chain
Limb segment free to move in multiple directions (eg. Leg Curl/Extention Open Kinetic Chain
Describe the Convex on Concave relationship Roll + Slide opposite to limb motion
Describe the Concave on Convex relationship Roll + Slide + Limb motion in the same direction
Force + distance btw force and axis of rotation Torque
Length between axis of rotation and perpendicular intersection of force Moment Arm + moment arm = + force
Load and Force Opposite, Joint in the middle First Class Lever (Head, Neck, and Cervical Muscles
Joint and Force Opposite, Load in middle Second Class Lever (Bracoradialis against Gravity)
Joint and Load are Opposite, Force in middle Third Class Lever (Brachradialis and Dumbell)
Direction of muscular force - determines the action of muscle Line of Pull
Only tissue able to regenerate 100% Bones
What makes up the axial skeleton? Skull, hyoid bone, vertebrae, robs
Function of the skeletal system? 1. Movement 2. Support 3. Protection 4. Mineral + Fat Storage 5. Blood pdt 6. Mineral homeostasis
What are the two bone tissue types? Cortical Compact Bone and Cancellous Porous Bone
What type of bone tissue absorbs compressive forces and is thickest around the shaft? Cortical Compact Bone
What type of bone tissue redirects force and resists local stress; little beams or trabeculae are present. Cancellous Porous Bone
What are the Types of Bones and an example of each? 1. Flat: Scapula 2. Long: Femur 3. Short: Carpals 4. Irregular: Vertebrae 5. Seasmoid: Patella
Joint Classification: Binds bones together, transmits force from one bone to another. Example? Synarthosis: Sutures of the skull
Joint Classification: Provides shock absorption and limits motion. Example? Cartilaginous or Ampiarthrosis: Intervertebral Disks
Joint Classification: Fluid filled, between 2 bones Diarthrosis
List examples of Diarthosis Joints Hinge Pivot Ball and Socket Ellipsoid Condyloid Saddle Plave
