Anatomy and Function
100
The study of human movement
What is kinesiology
100
These are the four categories of bones
What are long, short, flat, and irregular
100
The 6 types of synovial joints
What are ball and socket, gliding, hinge, pivot, condyloid, and saddle
100
The inability for a two-joint muscle shorten after it has already been contracted is known as
What is active insufficiency
100
This is the articulating joint between the femur and pelvis
What is the acetabulum
200
Two joggers run 8 miles north and 5 miles west. This is the shortest distance they would need to run in order to return to their starting position.
What is 9.4 miles
200
This term means that bones are directionally dependent, or have different strength and stiffness depending on the direction of the load.
What is anisotropic
200
This sensory receptor inhibits tension development in the agonist and initiates tension development in the antagonist.
What is GTO
200
Due to the force-velocity relationship, as force increases, velocity will respond in this way.
What is decrease
200
The gracilis, semitendinosus, and sartorius all insert to this common attachment site
What is the Pes Anserinus
300
When a 15 foot ladder is leaning on a building at 26 degrees with the building, the ladder will reach this height on the building.
What is 13.5 feet
300
The type of bone found along the diaphysis of a long bone
What is cortical bone
300
The stretch reflex is accomplished by this sensory organ
What are muscle spindles
300
Muscle having maximum strength at resting position describes this relationship
What is the length-tension relationship
300
The origin, insertion, and action of the rectus femoris
What is the AIIS, patella, and hip flexion/knee extension
400
The 5 pairs of movements that occur on the frontal plane
What are adduction/abduction, radial/ulnar deviation, lateral flexion, inversion/eversion, and scapular elevation/depression
400
The ability for bones to adapt based on frequently applied stresses and loads is know as
What is Wolff's law
400
These are the four behavioral properties of muscles
What are irritability, extensibility, elasticity, and contractility
400
The stretch shortening cycle is defined as this
What is an eccentric movement followed by a powerful concentric contraction
400
This muscle is essential for proper gait and stability, especially while on one leg.
What is the gluteus medius
500
This is the largest angle of a triangle with sides measuring 20m, 30m, and 40m.
What is 104.5 degrees.
500
Bone is weakest when resisting this force (1), and strongest when resisting this force (2).
What are (1) shear and (2) compression forces
500
This is the only band/zone of a sarcomere that does not change length during contraction.
What is the A band (dark band)
500
This is the time between the arrival of neural stimulation and tension development in a muscle
What is the electromechanical delay
500
The origin, insertion, and action of the gastrocnemius
Medial and lateral femoral condyles, calcaneus, plantar and knee flexion
