The Appendicular Skeleton

STUDY
PLAY
Appendicular skeleton
consists of 126 bones
two parts: upper and lower
Pectoral Girdle
this area of appendicular skeleton stabilizes the upper limbs.
It has two parts: the scapula and the clavicle
scapula and clavicle
two parts of the pectoral girdle
Scapula
this part of the pectoral girdle and is the major attachment site for muscles.
Clavicle
this part of the pectoral girdle is the bony link between the sternum and the scapula
Pelvic Girdle
this area of the appendicular skeleton positions and stabilizes the lower limbs, transfers weight of the body to the legs, and is make up of two hip bones, known as the two coxae bones.
Coxa
this component of the appendicular skeleton is made up of 3 fused bones.
Illium ischium and pubis
three bones that make up a coxa bone
illium
this is the large, superior, winglike bone of the coxa
ischium
this is the posterior and inferior part of the coxa bone
pubis
this is the anterior and inferior part of the coxa bone
acetabulum
this is known as the hip socket.
it is formed by the fusion of all three of the fused coxa bones.
2 coxa, sacrum, coccyx
name of the 4 bones that make up the pelvis
height, width, pelvic outlet, pubic angle
Characteristics that differ between makes and females in terms of their pelvis
HINT: there are 4
males
the gender that has a pubic angle of less than 90 degrees
females
the gender that has a pubic angle of greater than 90 degrees
articulations
this is the term for the point of contact between 2 bones
articulations
another word for joints
structure
this determines the degree and type of movement in terms of articulation
movement
this is the term for flexibility or range of motion
strong
immobile joints are this
weak
moblie joints are this
degree of movement
the functional classifications of joints is based on this
Synarthrosis
this is a type of functional classification of joints that is immovable and tightly connected (this is due to fibrous connective tissue)
synarthrosis
examples of this type of functional classification of joints includes sutures and gomphosis
suture
type of synarthrosis that is made of fibrous joint.
this is cranial bones
gomphosis
type of synarthrosis that is made of fibrous joint.
Example of this is teeth.
Amphiarthrosis
this is a type of functional classification of joints that is movable.
Amphiarthrosis
examples of this type of functional classification of joints includes symphysis and syndesmosis
symphysis
this is a type of amphiarthrosis that is made up of fibrocartilaginous pads.
Examples of this include the vertebrae (intervertebral discs) and pubic bones (the pubic symphysis)
syndesmosis
type of amphiarthrosis that is made up of ligamentous.
Example includes tibiofibular joint
Diarthrosis
a synonym for synovial
type of functional classification of joints that is highly movable.
it involves long bones and provides the largest range of motion
EX: shoulder, hip, elbow, phalanges
synovial joint
type of joint (synonymous with diarthrosis)
contains 4 parts
articular cartilage, synovial capsule, synovial membrane, synovial fluid
4 parts of synovial joint
articular cartilage
part of synovial joint that contains slippery hyaline cartilage
synovial capsule
part of synovial joint that surrounds the joint by a fibrous dense irregular connective tissue
synvovial membrane
part of synovial joint that lines capsules and secretes synovial fluid
synovial fluid
part of synovial joint that lubricates, absorbs shock, and distributes nutrients and waste.
fat pads meniscus ligaments bursa
these are the parts of the synovial joint accessory structures
fat pads
parts of a synovial joint that fills spaces of a joint
meniscus
part of synovial joint that is extra fibrocartilaginous pads
ligaments
part of synovial joint that reinforces and strengthens joints. it has two parts; extracapsular and intracapsular
bursa
part of synovial joint that is a synovial puch. it functions in separating moving parts.
Kinesiology
the study of the mechanics of movement
