chapter 8 Flashcards
what are joints known as
Are known as articulations
Functional junctions between bones
Bind parts of skeletal system together
Make bone growth possible
Permit parts of the skeleton to change shape during childbirth
Enable body to move in response to skeletal muscle contraction
bones make what possible
growth
Joints of the skeleton permits change for what
Permit parts of the skeleton to change shape during childbirth
what will be enable to move or response
Enable body to move in response to skeletal muscle contraction
classification of three main joints
Fibrous joints Cartilaginous joints Synovial joints
what is a fibrous joint
Dense connective tissues connect bones
Between bones in close contact
what is Cartilaginous joints
Hyaline cartilage or fibrocartilage connect bones
what is Synovial joints
Most complex
Allow free movement
what is synarthrotic joints
Functional classification: Synarthrotic joints Considered immovable Amphiarthrotic joints Slightly movable Diarthrotic joints Freely movable
what is Amphiarthrotic joint
Slightly movable
what is Diarthrotic joints
Freely movable
There are three (3) types of fibrous joints
Syndesmosis
Suture
Gomphosis
what tissue holds fibrous joints together
Dense connective
what is syndesmosis
A sheet or bundle of fibrous tissue connecting bones
syndesmosis lies between what
tibia and fibula
what is amphiarthritic
slight movement in the joint
what are suture
Between flat bones
where would you find a suture
skull
what kind of tissue is in the suture
Thin layer of connective tissue connects bones
suture is a classification of what
Synarthritic
what is Gomphosis:
Cone-shaped bony process in a socket
Gomphosis is classification of what
Synarthritic
cartilaginous are connected by what
hyaline or fibrocartilage
2 types of cartilaginous
Synchondrosis
Symphysis
what is synchondrosis
Bands of hyaline cartilage unite bones
what is the synchondrosis between
manubrium and the first rib (costal cartilages
what is symphysis
Pad of fibrocartilage between bones
we would find symphysis between what
Joint between bodies of adjacent vertebrae
most joints in the body are what
Synovial Most joints All are diarthrotic Consist of: Articular cartilage Joint capsule Synovial membrane Synovial fluid Menisci Bursae
synovial joints are classified of what
diarthrotic
Synovial joints consist of what
Articular cartilage
Joint capsule
in synovial joints what secrete fluids and what kind of fluid
Synovial membrane
Synovial fluid
what is Articular cartilage
hyaline cartilage found on articulating surffer
what is Joint capsule
holds the joint together, by way of an envelope, attached to the end of each bone at the joint, enclosing the cavity of a synovial joint
what is Synovial membrane
membrane that forms the inner lining of the capsule of a freely movable joint and secretes synovial fluid
what is Synovial fluid
moistens and lubricates the surfaces of the joint as well as supplying nutrients to the articular cartilage
what is Meniscus
fibrocartilage that separates the articulating surface of bones in the knee
what is Bursae
saclike fluid-filled cushioning structure, lined with synovial membrane, near a joint
you find this joint in the hip and shoulder
Ball & Socket/spheroidal Joint
where would u find Condylar/ellipsoidal Joint
between metacarpals and phalanges
Between radius and carpals
where you find Plane/gliding Joint
Between carpals
Between tarsals
Between facets of adjacent vertebrae
where would you find Hinge Joint
Elbow joint
Between phalanges
where would you find Pivot/trochoid Joint
between atlas (C1) and dens of axis (C2)
where would you find Saddle/sellar Joint
Between carpal and 1st metacarpal of thumb
Movement at a joint occurs when a muscle contracts and what is pull
Movement at a joint occurs when a muscle contracts and its fibers pull its moveable end (insertion) towards its fixed end (origin).
Movement at a joint occurs when a muscle contracts and
after its pulled it moves towards what
towards its fixed end (origin).
