Chap8 appe.


appendicular skeleton includes bones of the upper and lower extremities and the shoulder and hip girdle
The appendiuclar skeleton primarily to facilitate movement - pectoral girdle-pelvic girdle-upper limbs-lower limbs
___ or _____ girdle attaches the bones of the upper limbs to the axial skeleton pectoral or shoulder girdle
pectoral or shoulder girdle consists of scapula and clavical
clavical articulates wtih sternum sternoclavicular joint
clavical articulates with scapula acromioclavicular joint
scapula help in place by muscle only
upper limb attached to pectoral girdle at shoulder gelnohumeral joint
the ___ or _____ lies horizontally in the superior and anterior part of the thorax clavical or collar bone
the clavical trasmits what mechanical force from the upper limb to the trunt (why broken so easily)
Clavical extends from sternum to scapula above first rib
clavical lies ___ to the first rib superior
Clavical articulates with sternum and the clavical
The scapula or shoulder blade articulates with clavical and the humerus
the subscapular fossa is filled with muscle
the ____ in the scapula is for muscle attachment coracoid process
____ ____ forms shoulder joint with head of humerus glenoid cavity
_____ & ______ fossa for muscular attachments supraspinous and infraspinous fossa
longest and largest bone of upper limp humerus
articulates proximally with the scapula and distally at the elbow with both radius and ulna humerus
greater and less tubercles for muscle attachment
on the distal end of the humerus it forms what joint with ulna and radius elbow joint
on humerus articulates with head of radius (cap) head capitulum
on humerus- articulartion with ulna trochlea
on humerus- posterior depression for olecranon process of ulna olecranon fossa
on humerus- attachment of forearm muscles medial and lateral epicondyles
located on medial aspect of forearm ulna
located on lateral aspect of forearm radius
ulna and radius articulate with the? humerus at the elbow joint, with each other and 3 carpal bones
on ulna- trochlear notch artiulates with humerus
on ulna- radial notch articulates with radius
on radius- head articulates with capitulum of humerus & radial notch of ulna
tuberosity on radius is for muscle attachment
elbow joint articulates with articulation of humerus with ulna and radius
ulna articulates with trochlea of humerus
radius articulates with capitulum of humerus
interosseous membrane between ulna and radius provides site for muscle attachment
styloid process of ulna is head separted from wrist joint by firbocartilage disc
radius forms wrist joint with scaphoid, lunate and triquetrum
provides a strong and stable support for lower extremities on which weight of body is carried pelvid (hip) gridle
each hip bone (coxal bone) is comprised of 3 sep. bones at birth -ilium-pubis-ischium
ilium, pubis and ischium fuse at the ____ which forms the socket for the hip joint acetabulum
____= two hipbones united at pubic symphysis pelvic girdle
pelvic girdle articulates posteriorly with sacrium at scaroiliac joints
____ ____= 2 hip bones, sacrum and coccyx bony pelvis
larger of 3 components of hip bone illium
illium artciulates (fuses) with the ischium and pubis
the ischium is the ____, _____ portion of the hip bone inferior, posterior
the pubis is the ____ and ___ part of hip bone anterior and inferior
illiac crest and iliac spines for muscle attachment
greater sciatic notch for sciatic nerve is formed by ilium
____= sacrum, coccyx and 2 hip bones pelvis
sacral promontory to symphysis pubis pelvic brim
pelvic brim separates flase from true pelvis
false pelvis holds only abdominal organs
path of babies head= pelvic axis
together with the sacrum and coccyx and two hipbones form the pelvis
The pectoral girdle does not directly articulate with veterbal column; the ___ girdle does pelvic
the _____ girdle sockets are shallow and maximize movements pectoral
those of the ____girdle are deeper and allow less movements pelvic
the structure of the ____ girdle offers more movement than strengh pectoral girdle
the ___ girdle more strength than movement pelvic girdle
is largest, heavist and strongest bone in body femur
femur articulates with the hip bone and tibia
the head of femur articulates with acetabulum (attached by ligament of head of femur)
the medial and lateral condyle of femur articulate with tibia
on the femur the ___ is common fracture site neck
muscle attachments in femur greater and lesser trochanter, linea aspera, gluteal tuberosity
____ ____ is visible anteriorly between condyles patellar surface
sesamoid bone located anterior to the knee joint patella or knee cap
It functions to increase the leverage of the tendon of the quadriceps femoris muscle, to maintain the position of the tendon with knee is bent and protect knee joint patella
increases what of quadricept femoris tendon leverage
larger,medial, weight-baring bone of leg tibia
fibula is ___ and ___ to tibia parallel and lateral
in tibia the tibial tuberosity is for patellar ligament
fibula is not part of knee
when standing, weight is on what two bones of foot talus and calcaneous
the talus= what bone? and articulates with? ankle bone; tibia and fibula
heel bone calcaneous
big toe= hallux
arches of the foot functions? distribute body weight over foot
