Chapter 14 Flashcards
An articulation (joint) is
The point of contact between bones
Every bone connects to at least on other bone except
The hyoid bone
Joints allow for
Movement
Articulations can be classified according to ___ or ______
Structure or function
3 structure classifications of articulations, named by the connective tissue at the joint
Fibrous, cartilaginous, and synovial
Articulation classifications by function
Synathroses (no movement)
Amphiarthroses (slight movement)
Diathroses (free movement)
Sutures
Fiborous, synarthroses, no movement
Pubis symphysis
Cartilaginous, amphiarthoses , slight movement
Shoulder
Synovial, diarthroses, free movement
Fibrous synathroses subtypes
Syndesmoses
Sutures
Gomphoses
Syndesmoses are
And example
Ligaments connect to the bone
Distal raioulnar joint
Sutures are only found in the ____ and have
Only found in the skull and have interlocking teeth like projections that connect to bones
Gomphoses are
Joints between teeth roots and jaw bones
Cartilaginous (amphiarthroses) subtypes
Synchondroses
Symphyses
Synchondroses is
2 examples
What is a temporary example
Hyaline cartilage between bones
Between sphenoid and occipital
Between 1st rib and sternum
Growth plate is temporary
Symphyses is a
2 examples
________ movement
A pad or disk of fibrocartilage connects the bones
Pubis symphysis and between vertebrae
Limited movement
Synovial diarthroses subtypes are __________, the _____________ in the body, the most ________ in the body. Most joints of the ______ are them
Freely moveable
Most numerous
Most complex
Most joints are of appendicular
7 structures of synovial (diathroses) joints
Joint capsule Synovial membrane Articular cartilage Joint cavity Menisici Ligaments Bursae
The joint capsule is a _______ casing around the two joining bones
It is made of _______ ______________
Lined with______
firmly attached to _______ of each bone at ______
It is actually an ________ of the ______
Provides a _______ while allowing ________
Sleeve like
Made of strong fiborous connective tissue
Lined with synovial membrane
Attached to shaft at the peristeum
Extension of the periosteum
Secure attachment while allowing movement at joint
Synovial membrane is the _______
It _______________ which lubricate joint
It _______ movement
Lining of joint capsule
Secrets synovial fluid
Facilitates movement
Articular cartilage is ______________ cartilage
It is ___________
covers _________
Decreases _______
And absorbs _______
Thin layer of hyaline cartilage
Rubbery/smoot
Covers ends of bones at joints
Decreases friction
Absorbs jolts
Joint cavity is
Small space between articulating surfaces of the 2 bones of the joint
The menisci or articular disk are pads of _______ between ______ of some _______ joints
They _____ joint cavity into _____
Fibrocartilage between articulating bones of some diathrotic joints
Divide joint cavity into 2 separate spaces
Ligaments are _____ made of tough fiborus _______
Originate from the ________
Attach ________
Bands, connective tissue
Periosteum
Bones together
Burase are _____
Cushion some ______ to cushion joint and to _________
Synovial fluid filled sacs
Boney joints
Facilitate tendom movement
Uniaxial joints permit
Movement around one axis and only around one plane
2 examples of uniaxial joints
Hinge and pivot
Biaxial joints permit
Movement around 2 perpendiculare axes and 2 perpendicular planes
2 examples of biaxial joints
Saddle
Condyloid
Multiaxial joints permit
Movement around 3 or more axes and 3 or more planes
Example of multiaxial joints
Ball and socket and gliding
2 Example of ball and socket joint
Ball and socket allows ________
Shoulder and hip
Widest range of movemnt
Hinge joint allows ______ and 3 examples
Flexion and extension
Elbows knees and fingers
Pivot joint allows
1 example
Rotation
Cervical neck vertebrate

Between vertebrae
Condyloid joints allow for
2 examples
