Cards in this deck (43)
- 1What is a joint?A point where bone connects. It is a structure that provides support and movement
- 2What are three types of joints based on structural classification?1. Fibrous joints
2. Cartiliginous joints
3. Synovial joints - 3Which joint is stationary? Where is it commonly found?fibrous joints; they are commonly found in the skull where the sutures join together
- 4Which joint allows for slight movement?cartilaginous joints; the 32 intervertebral joints are fall under this classification
- 5The functional classification of joints: Synarthrosis: ___________ joint ____________: movable joint ____________: freely movable jointSynarthrosis: immovable joint
amphiarthrosis: movable joint
diarthorsis: freely movable joint - 6Axillary articulations are also known as the joints of the _________.joints of the shoulder
- 7Sternoclavicular joints refer to the joints betweenThe sternum and the clavicle
- 8The hip joint is an articulation between of pelvis with the ____________. Is it a _______ __________ _______.femur
- 9List all the important features of a synovial jointArticular cartilage
joint capsule
joint cavity
bursae
instrinsic & extrinsic ligaments - 10Articular cartilage is located on the ______ of the bone that comes in contact with one another. This __________ cartilage protects the end of bone and allows for a smooth contact surface for the bone to move about.end of the bone;
hyaline cartilage - 11What are ligamentsVery strong fibrous tissues that do not stretch much; they hold the bones together and form the joints.
- 12What are the two types of ligaments?Intrinsic and extrinsic ligaments; they work together to ensure strong connections
- 13What joint have the most ligaments?The knee has four very thick ligaments as it bears all the stress
- 14The joint capsule is a __________ structure the holds everything in the joint together and aids in ligaments.bag-like
- 15What are the two layers of the joint capsule and what are their functions?1.Synovial membrane:
Produces the fluid inside our joint that plays a significant role in lubrication
2.Fibrous layer:
Supports the structure on the outside of it - 16What is the joint cavity?the space between the bones in a synovial joint. It is filled with synovial fluid
- 17The joint cavity also provides nutrients for the articulating cartilage True or false?True
- 18Intrinsic ligaments helpthicken and reinforce the joint capsule
- 19Extrinsic ligamentsseparate from the joint capsule to reinforce the joint the joint by attaching the bones together
- 20A dislocation occurs whena bone is displaced from its original location (i.e the bone slips out of its joint)
- 21Dislocations most commonly occurat the shoulder and in the fingers
- 22The 3 symptoms of dislocation include1. limited movement
2. swelling and bruising
3. visibly deformed structure. (i.e the structure is out of space) - 23When we injure our joints, the most obvious part that swells up is thejoint capsule
- 24A separation occurs whenligaments that connect bones together tear away. The ligaments must TEAR in the case of SEPARATION, but not in the case of dislocation
- 25What are the 3 types of cartilage1. Hyaline cartilage
2. Fibrocartilage
3. Elastic cartilage - 26Which is the weakest and strongest kind of cartilage?weakest: Hyaline cartilage
strongest: fibrocartilage - 27List three places where the elastic cartilage is found.External ear; epiglottis; larynx
- 28What are shin splintsThe pain felt along the edges of your tibia that results from the tearing of muscles and membranes
- 29Give 4 things that contribute to acquiring shin splints1. Inadequate stretching
2. Worn shoes
3. Sudden increase in the intensity of exercise
4. Jumping and running type activities - 30The acronym SHARP stands forS: Swelling
H: Heat
A: Altered function/appearance
R: Redness
P: Pain - 31When a bruise turns from purple to green and yellow, it means thatit is healing
- 32The acronym PIER and RICEare treatments for soft tissue injury
- 33What does PIER stand for?P: Pressure
I: Ice
E: Elevation
R: Rest/restriction - 34What does RICE stand for?R: Rest/restriction
I:Ice
C: Compression
E: Elevation - 35Blood vessels and nerves pass through the joint tissue but the _________ and _________ are avascularcartilage and ligaments
- 36Bursae aresmall, flattened fluid sacs found at the friction points between tendons, ligaments and bones.
- 37Ligaments are referred to as _________ stabilizers whereas tendons that connect ________ to bone are also known as ____________ stabilizers.Ligaments: static/joint stabilizer
Tendons: dynamic/muscle stabilizer - 38Ligaments do not stretch as much as tendons, and when they reach their max, they usually tear. True or falseTrue
- 39The periosteum allows for the attachment of ligaments and tendons True or falseTrue
- 40What is a sprain?Injury of a ligament or joint
- 41What is a strain/pull?Injury of a tendon/muscle
- 42Why should we elevate the injured part?To ensure that blood goes back in the opposite direction (towards the heart);
too much blood isn't good - 43What is osteoarthritis?A condition involving loss of cartilage at joints whereby bone becomes exposed and damaged.
