What are synarthroses, amphiarthroses, and diarthroses ?
Functional classification from immovable to slightly movable to freely movable.
|
What is flexion and extension?
Types of angular movement that increases or decreases the angle between bones.
|
What is contractility, excitability, extensibility, and elasticity?
Four functional properties/characteristics of skeletal muscle
|
What is intercostals?
external- pulls ribs toward each other to elevate ribcage, internal- draws ribs together to depress ribcage.
|
What is tendonitis?
This condition is characterized by inflammation of a tendon
|
What are synchondroses and symphysis?
These are the two types of Cartilaginous Joints.
|
What is multiaxial?
Means movement can occur around all three axes and along all three body planes: frontal, sagittal, and transverse.
|
What is axon terminal, synaptic cleft, and sarcolemma of muscle fiber?
These are the three structural components of a neuromuscular junction
|
What is extensor carpi radialis?
Extends wrist and abducts wrist
|
What is fibromyalgia?
This is a mysterious chronic pain syndrome of unknown cause.
|
What are sutures, syndesmoses, and gomphoses?
Three types of Fibrous Joints.
|
What is abduction?
From latin words meaning "moving away" this is movement of a limb away from the body midline
|
What is epimysium, perimysium, and endomysium?
Connective tissue that holds fibers of skeletal muscle together in order from external to internal.
|
What is rectus femoris?
extends knee and flexes thigh at hip
|
What is Duchennes Muscular Dystrophy?
The most common form of muscular dystrophy?
|
What are plane, hinge, pivot, condylar, saddle, and ball & socket (pick two)?
Two of the six types of synovial joints.
|
What is knee joint?
The largest and most complex joint in the body. Primarily acts as a hinge but also permits some medial and lateral rotation.
|
What is myofibrils?
A contractile, rod shaped organelle that makes up more than 80% of the sarcoplasm.
|
What is pectoralis major?
Mover of arm flexion, rotates arm medially, abducts arm
|
What is Dislocation?
Luxation and subluxtion are examples of this joint injury?
|
What is syndesmoses?
In this type of Fibrous joint, the bones are connected exclusively by ligaments and is amphiathrosis.
|
What is carpometacarpal joints of the thumbs?
An example of a saddle joint
|
What is sliding filament model?
Concentric contraction that is initiated by release of calcium ions which are powered by ATP. During contraction, myosin heads bind to actin, detach and bind again to propel thin filaments toward the M line.
|
What are internal/external obliques?
Flex vertebral column and compress abdominal wall, trunk rotation and lateral flexion
|
What is Bursitis?
Housemaid's knee and students elbow are examples of this condition
