Chapter 9: Joints Flashcards
Joints ____ categorized by structure
are
A Synarthrosis is a immovable joint, name one
suture
A Amphiarthrosis is a
slightly movable joint
A Diarthrosis is a
freely movable joint
2 Kinds of joints:
Symphysis and Synovial
Synarthrosis Joint: not a
movable joint
Synarthrosis Suture
is the skull joints
Gomphosis is a Synarthrosis joint of Periodontal Ligament
that binds teeth to the jaw
Synchondrosis: a rigid bridge between
2 articulating bones
Synostosis is a totally immovable joint.
Fused together
Syndesmosis -
bone connected by ligaments
Symphysis- articulating bone connected by a
wedge or pad of fibrocartiliage (Pubic Bones)
Diarthrosis- Synovial joints,
wide range of motion and generally at end of a long bone
Synovial joints are
freely movable
Synovial joints are surrounded
by a Articular Capsule
Synovial joints can’t be movable ____ and strong
and
Articular cartilage surfaces are
slick and smooth and prevents contact between bone
Articular surfaces don’t touch each other,
separated by Synovial fluid
Synovial fluid (Membrane): lubricates, and
distributes nutrients and absorbs shock
Cartilage is a
meniscus pad between opposing bones
Ligaments are for
support and strength
Extracapsular Ligament ___
is outside the joint
Intracapsular ligaments ____
are inside the joint
Bunions ____ caused by high heels and pointy toed shoes
are
Tendons ____
are not part of the joint, connect muscle to bone
Tendons function
are to stabilize, connect muscle to bone
Bursae: small fluid pockets ____
in connective tissues and reduces friction
Adduction:
inward or together
Abduction:
outward or away
Arm movement:
up is flexion, rearward is hypertension
Head movement:
forward is flexion and down is extension
Circumduction :
complete circular motion of a limb
Medial Rotation: _____
Is a internal rotation
Lateral Rotation ____
is a External Rotation
Pronation:
back of hand ___ view
Supination:
palm ____ hand in view
Plantar Flexion: ____
Is standing on toes
Lateral Flexion: is
Spine is bent side to side
Intervertebral joints are
between adjacent vertebrae
Intervertebral Disc: Collagen fibers attach disc ___
to adjacent vertebrae
Intervertebral ligaments: Ligamenta Flava
connect Laminae to adjacent vertebrae
Longitudinal ligaments: ____
fiberous band that parallels anterior leg
Interspinous: longitudinal fiberous band ____
that attaches Spinous Process from C7 to Sacrum
Intervertebral Joint - Nuclius Pulposus
gelatinal core, provides smooth movement of spine
Joint between adjacent vertebrae ____
is a symphysis
Anterior joint between 2 pubic bones _____
is a symphysis
Joints between long bones _____
is a Diarthroses
Articular Cartilage reduces friction _____
and prevents bony surfaces from contact
Synovial fluid, absorbs shock, nutrient distribution _____
and lubrication
Tendons limit range of motion in _____
In a a joint
Dislocation ____
is loss of contact between two articulating surfaces
Abduction and Adduction refers to
movement in the Appendicular Skeleton
Rotation of the forearm posteriorly ____ pronation
is
Saddle joint allows angular movement ____ not rotation
but
Standing on tip toe, example ____ extension
of
Elbow _____ Knee joints permit angular movement in a single plane
and
Flexion decreases ____ angle between bones
the
Shoulder ____ Hip joints are “ball and socket”
and
Intervertebral Disc: Anulus Fibrosus ____ Nucleus Pulposus structures
and
Subacromial, Subcoracoid ______ Subscapular Bursae reduces friction in the shoulder
and
The knee joint represents 3 separate ____
joints
A meniscus subdivides synovial cavity _____ channels flow of synovial fluid
and
Osteoporosis decreases height _____ reduction of water in the nucleus pulposus
by
Plane joint (gliding), Clavicle ____ Sternum
and
Hinge joint _____ an elbow
is
Condylar joint, Radius _____ carpal bones
and
Saddle joint ___ the thumb
is
Pivot joint, Atlas ___ Axis
and
Ball ____ socket joint, shoulder
and
Cartilage does not have blood vessels, they depend ___ diffusion for nutrients
on
