Joints Flashcards
Two types of fibers within the fibrous component of the extra cellular matrix
Collagen and elastin 
Why are complex joints more likely to be affected by injury, disease, or aging?
Because complex joints have more parts and are subject to more wear and tear than simple joints
Describe simple joints versus complex joints
Simple joints or less mobile and more stable
Complex joints allow greater mobility and are less stable
Dense, fibrous, connective tissue that is attached to the bone and forms a sleeve around joint, sealing the joint space
Joint capsule 
Flat sack of synovial membrane in which the inner sides of the sac are separated by fluid film. Located where moving structures are apt to rub against each other.
Bursa
Type of cartilage that consists primarily of collagen, fibers, and forms the cement in joints that permits little motion
White fibrocartilage 
Type of cartilage found in the ear and epiglottis and has a higher ratio of elastin  to collagen fibers
Yellow elastic cartilage
Type of cartilage that forms a thin covering of articular cartilage on the ends of bones in freely moveable joints. Helps absorb the pressure imposed on the joints.
Hyaline cartilage 
The combination of resistance offered by a fluid to a change of form, and the ability of material to return to its original state after deformation
Viscoelasticity 
The ability of a material to return to its original state after being stretched
Elasticity
Resistance to a change of form offered by a fluid
Viscosity 
The slow movement of viscoelastic materials back to their original state and tissue structure after release of a deforming force
Creep
The most complex joint design is likely to function in____
Mobility
What type of cartilage is found in joints that function primarily for mobility?
Hyaline cartilage
An important component of connective tissue that supports pliability is____
Water
The viscoelastic quality of connective tissue to modify them in the direction of the force applied, and then slowly return to the original state is called
Creep
Which of the following joint types, has the most limited mobility
Syndesmosis
Which of the following is not a characteristic of a synovial joint?
The joint capsule is formed a fibrous tissue
Bones are separated by fibrocartilage
Hyaline cartilage covers the joint services
Synovial fluid forms a, lubricating film over the joint services
Bones are separated by fibrocartilage
Which joint structure is highly innervated, and a source of sensory data, concerning movement and position of a joint
Stratum fibrosum
The accessory movements at a joint that describes how articulating surfaces move within the joint capsule and contribute to joint play are called
Arthrokinematic’s
The closed packed position of a joint can be described as
Convex surface fitting with maximal contact into the concave surface
Which type of ROM is a neurological protective mechanism for normal joint function?
Physiological range of motion
The term used to describe the movement of the scapula toward the spine is
Retraction
A ball and socket joint is also considered a———joint
Multiaxial
The name of the association between joints as they function in a relationship to each other is
Kinematic chains
The function of joints that often results in a compensation pattern in one joint if a change in function occurs in another joint is called the
Closed kinematic chain
The two articulating bones of the temporomandibular joint are the
Mandible and temporal
The glenohumeral joint has extensive mobility because
It has range of motion limits provided, primarily by soft tissue
Which movement is allowed at the sternoclavicular joint? Flexion, rotation, inversion, or extension?
Rotation
The Corococlavicular ligament is part of what joint
Acromioclavicular
Which of the following joints is responsible for pronation?
Radioulnar
A wrist movement is greatest in flexion and extension, because
The joint capsule is loose in the superior and inferior directions
The joint where the fingers are in the body of the hand is called the
Metacarpophalangeal joint
The articulating bones of the sacroiliac joint are the
Sacrum and the iliac
Which of the following joint has no direct muscle action, but is responsible for helping the vertebral column to remain relatively still during walking?
Sacroiliac
Which fibrocartilagenous structure allows for more surface contact at the femur on the tibia
Menisci
The most stable position of the ankle joint is
Full dorsiflexion
Which joint allows rotation as a motion pattern
Atlantoaxial
Which two joints are most active during breathing
Costovertebral and costochondral
What is the action of the ribs during inspiration?
Ribs are raised
