appendicular
Question | Answer |
---|---|
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 |
