Joints Flashcards
cartilaginous joints
articulating bone ends are connected by cartilage.
what type of joint are the intervertebral joints, and the pubic symphysis?
cartilaginous joints
Synovial joints
articulating bone ends are separated by a joint cavity containing synovial fluid. All synovial joints are diarthrosis.
fibrous joints
articulating bone ends are joined by fibrous tissues. Two types, sutures, and sydnesmoses
sutures
irregular edges of bones interlock and are joined by short connective tissue fibers.
syndesmoses
articulating bones are connected by short ligaments of dense fibrous tissue, bones do not interlock
Is the following a cartilaginous, fibrous, or synovial joint? typically allow a slight degree of movement
cartilaginous
Is the following a cartilaginous, fibrous, or synovial joint? include joints between the vertebral bodies and the pubic symphysis
cartilaginous
Is the following a cartilaginous, fibrous, or synovial joint? essentially immovable joints
fibrous
Is the following a cartilaginous, fibrous, or synovial joint? sutures are the most remembered examples
fibrous
Is the following a cartilaginous, fibrous, or synovial joint? cartilage connects the bony portions
fibrous
Is the following a cartilaginous, fibrous, or synovial joint? have a fibrous articular capsule lines with a synovial membrane surrounding a joint cavity
synovial
Is the following a cartilaginous, fibrous, or synovial joint? all are freely moveable or diarthrotic
synovial
Is the following a cartilaginous, fibrous, or synovial joint? bone regions are united by fibrous connective tissue
fibrous
Is the following a cartilaginous, fibrous, or synovial joint? include the hip, knee, and elbow joints
synovial
What is the joint between most skull bones?
Suture
What is the joint between the axis and the atlas?
pivot
What type of joint is the hip joint?
ball and socket
what is the joint between the forearm bones and wrist?
condyloid
what kind of joint is the elbow?
Hinge
what kind of joint are the interphalangeal joints?
hinge
what kind of joint are the inter carpal joints?
plane
supination
Moving the palm from facing posterior to an anterior position
pronation
moving the palm from the anterior position (anatomical position) to the posterior position
eversion
lateral turning of the sole of the foot (rolling your ankle on the outside of it)
inversion
a movement that results in the medial turning of the sole of the foot. Ankles rolling towards the arches.
plantar flextion
pointing the toes
dorsiflextion
flexing ones feet
flexion
decreases the angle of the joint and reduces the distance between two bones.
extension
increases the angle of a joint and the distance between two bones.
rotation
turing around on a logitunial axis, such as the C1 C2 and the radius around the ulna.
abduction
movement of a limb away from the midline or the body.
adduction
movement of a lim toward the midline of the body.
Circumduction
combo of flexion, extension, abduction, and adduction. Seen in ball and socket joints.
hinge
plane
saddle
condyloid
pivot
ball and socket
Ligament
joint cavity (contains synovial fluid)
articular (hyaline) cartilage
fibrous capsule
synovial membrane
periosteum
Articular capsule
•Synarthroses
–Immovable joints
•Amphiarthroses
–Slightly moveable joints
•Diarthroses
–Freely moveable joints
•Fibrous joints
–Generally immovable
•Cartilaginous joints
–Immovable or slightly moveable
•Synovial joints
–Freely moveable
–Syndesmoses
- Allows more movement than sutures but still immobile
- Example: Distal end of tibia and fibula
–Gomphosis
•Immobile fibrous joints.
Only seen in connecting the teeth to the mandible and maxilla
•Bursae
—flattened fibrous sacs
–Lined with synovial membranes
–Filled with synovial fluid
–Not actually part of the joint
•Tendon sheath
–Elongated bursa that wraps around a tendon
Joint cavity containing synovial fluid
articular (hyaline) cartilage
synovial membrane
fribrous layer of the articular capsule
Acromion of scapula
ligament (twice)
brusa
Tendon sheath
tendon of the biceps muscle
Connie = Condylar
Siddled = Saddle
Politely = Plane
Past = Pivot
Harry’s = Hinge
Brother = Ball and socket
Connie = Condylar; eg. Metacarpalphalangeal OR Metatarsalphalangeal (“knuckle”)
Siddled = Saddle; eg. Carpometacarpal of thumb OR Talocalcaneal of ankle
Politely = Plane; intercarpal of wrist OR intertarsal of ankle
Past = Pivot; proximal radioulnar joint OR C1 on C2 in spine
Harry’s = Hinge; humeroulnar joint at elbow OR Tibia and Talus at ankle
Brother = Ball and socket; shoulder OR hip
