material for intellectual nourishment.
What is synostosis?
Sutures completely fused.
Hyperextension
(above normal)
 
extension of a joint beyond 180 degrees
 
EX: Glancing up at the ceiling while standing, your neck is hyperextended
movement that closes the mouth
elevation
Knee (describe joint)
Tibiofemoral joint**Hinge jointlateral and medial meniscifibular and tibial co-lateral jointsanterior and postier cruciate ligamentspatellar ligament/quadriceps tendon
Movement in the anterior/posterior plane that reduces the angle between bones is known as _________.
Flexion
iniquitous
characterized by injustice or wickedness; wicked; sinful.
What type of movement is gomphoses?
synarthrosis
Ligaments
are composed of dense regular connective tissue
Synovial Membrane
composed primarily of areolar connective tissue
 
covers all the internal joint surfaces not covered by cartilage
 
lines the articulare capsule
localized movement angle foot to point outward
eversion
Symphyses
held together by fibrocartilage.. ie, pubic symphysis - cartilaginous
Cartilaginous joints
no cavity presentcartilage joins bonessome synarthrosis or amphiarthrosis
recalcitrant
resisting authority or control; not obedient or compliant; refractory.
diaphanous
very sheer and light; almost completely transparent or translucent.
assiduous
constant in application or effort; working diligently at a task; persevering; industrious; attentive:
examples of synovial joints
glenohumeral, temporomandibular, elbow, knee
_______ is bending of a body part
Flexion
Atlanto-occipital
Superior articular facets of atlas and occipital condyles of occipital bone
 
Synovial (condylar) joint
Diarthrosis
Extension and flexion of the head; slight lateral flexion of head to sides
Intrinsic Ligaments
represent thickenings of the articular capsule itself

extracapsular ligaments outside the articular capsule


intracapsular ligaments within the articular capsule
when the nucleus pulposus breaks through the anulus and enters the vertebral canal the result is an
herinated disc
Gouty Arthritis
uric acid crystals, heredity, common in men, defect in protein metabolism
-shortening of the muscle-movement is accelerated (enhanced)- \"winning against gravity\"
Isometric Contraction
movement of the thumb at the carpometacarpal joint in which the thumb moves across the palm to touch the finger on the same hand
opposition
Joints that allow extensive angular motion w/o axial rotation, as in twiddling your thumbs is known as _________.
Saddle joints
symphses joints found in
pubic symphysis, intervertebral discs
What joint is between the tibia and the femur?
hinge-uniaxial
_____ is movement at ankle that brings the foot farther from the shin.
Dorsilfexion
Circumduction
is a sequence of movements in which the proximal end of an appendage remains relatively stationary while the distal end makes a circular motion
Lumbosacral
Body of the fifth lumbar vertebra and base of the sacrum
 
Inferior articular facets of fifth lumbar vertebra Superior articular facets of first sacral vertebra
 
Cartilaginous joint (symphysis) between lumbar body and base of sacrum
synovial (plane) joint between articular facets
 
Amphiarthrosis between body and base diarthrosis between articular facets
 
Extension, flextion, lateral flexion of vertebral column
the tough outer layer of fibrocarilage on the interverbal discs is
anulus fibrosus
Inversion
unique to the feet, soles are turned medially
the _____ of the fibrous capsule prevents bones from dislocating
tensile strength
Sutures (Fibrous)
bones of the skull-very short CT Fibers
ankle extension is also known as _______.
Plantar Flexion
gadabout
a person who moves about restlessly or aimlessly, esp. from one social activity to another.
What type of joint is between the patella and the femur?
gliding joint
Diarthrosis-
accessory structures
BURSAE
- fluid filled pockets in CT that occur where a tendon or ligament rub against another tissue; function is to reduce friction
Nucleus Pulposus
is the inner gelatinous core of the disc and is primarily composed of water, with some scattered reticular and elastic fibers
Movement that occur at the shoulder and hip represent the actions that occur at which joint?
ball and socket
anterior surface of the bone is turned away from the midline
lateral rotation
To move your head from left to right as in saying no, is called_________.
Rotation
where are bursas found
where bones, ligaments, muscles, skin, tendons overlie and rub together
The structure of a ____ _____ is a convex surface one one bone articulating with a concave surface of another bone.
Saddle joint
Syllables and how they develop
important unit in early sound development
CV- consonant/vowel- Universal element of lang.
easy to perceive early and produce early
most kids learn to produce consonants in the initial position of syllables
ligaments and tendons are both made of
dense regular connective tissue
The six major types of synovial joints are
Ball-and-socket, condyloid, gliding, hinge, pivot, and saddle.
the hip is a _______ joint.
the knee is a _______ joint.
What are the three names given to the types of movement found in joints?
synarthrosis, amphiarthrosis, and diarthrosis
What are the 6 characteristics of a Synovial joint?
1 a joint capsule=articular capsule=thick layer of dense C.T.
2 Articular cartilages-shock absorbers and reduce friction.
3 A joint cavity filled with synovial fluid.
4 an synovial membrane-lining joint capsule(stops at edge of aticul. cart.) produces synovial fluid.
5 Accessory structures- Meniscus, fat pads, ligaments, tendons, and bursae.
6 Sensory nerves and Blood vessels.
The shoulder joint is the where what two bones articulate?
head of the humerous and glenoid cavity of scapula
