appendicular skeleton (how many borns, forms?)
126 bones that form limbs, pectoral, and pelvic girdles
function of appendicular skeleton
facilitates locomotiona nd manipulation of object (grabbing stuff)
what does the pectoral girdle connect
upper limbs to trunk and consists of clavicles and scapulae
what is the clavicle; what does it articulate on the medial end
S-shaped bone; medial end articulates w/ manubrium of sternum creating sternoclavicular joint
lateral end of clavicle articulates with
acronium of scapula to form acromiclavicular joint
scapula what is it?
broad, flat, triangular bone
the glenoid cavity of the scapula articulates with the (finish sentence)
glenohumeral joint
regions of the upper limb
arm (brachium), forearm (antebrachium), and hand
each upper limb contain _ bones
30
bones of arm
humerus
bones of forearm
radius (lateral) and ulna (medial)
bones of hand
carpals (wrist), metacarpals (palm), phalanges (fingers)
what the humerus articulate with (3 things)
proximally the scapula and distally the radius and ulna
proximal articulation of humerus (what is it)
head articulates with the glenoid cavity of scapula to form shoulder joint
distal articulations of humerus
trochlea medial with ulna, capitulum lateral with radius to form elbow joint
coronoid fossa (what it do)
anterior portion, receives coronoid process of ulna
radial fossa
anterior, receives head of radius
olecranon fossa
posterior, receives olecranon process of ulna
ulna is positioned
medially
radius is postioned
laterally
ulna olecranon forms the
elbow point
ulnat trocdhlear notch articulates with the
humerus
ulna coronoid process forms the
inferior margin of the trochlear notch
radial notch of ulna articulates with the _ and forms the
radius and forms the proximal radioulnar joint
ulnar styloid process is a
connective tissue attachment point
radial head articulates with the (2 things)
capitulum of humerus and radial notch of ulna
radial tuberosity is a (attachment)
biceps brachii attachment point
radial styloid process stabilizes
wrist joint
ulnar notch articulates with head of (to form?)
ulna to form distal radioulnar joint
pelvic girdle is copmosed of ?
2 hip (coxal) bones
what are the hip bones formed by
fusion of the ilium, ischium, and pubis
pelvis includes (bones)
coxal bones, sacrum, coccyx
ilium (what is the region)
superior & largest
ischium (region)
postinferior region
what bears weight when sitting
ischial tuberosity
pubis (region)
anterior region
what does the pubic symphysis do and how
unites left and right hipbones via fibrocartilag
acetabulum
deep socket for articulation w femur creating hip joint
obturator foramen; what is it covered by and its function
covered by collagen fibers serving as a muscle attachment site
articulates with sacrum forming sacroiliac joint
auricular surface
thigh bone
femur
longest and heaviest bone of lower limb
femur
leg bones
tibia and fibula
what bone is the medial portion, serving as a weight bearer
tibia
bone thats lateral, serving as muscle attachment site
fibula
foot bones
tarsals, metatarsals, phalanges
head of femur articulates w/ __ to form __
acetabulum to form hip joint
greater and lesser tronchanters, linea asepra
muscle attachment sites
condyles function
articulate with tibia to form knee joint
patella
sesamoid bone embedded in quadricepts tendon
ligament attachments of patella and their direction
quadriceps tendon (superior/anterior), patellar ligament (inferior, anterior)
tibia condyles articulate with
femur to form knee joint
tibial tuberosity
patellar ligament attachment
fibula head articulates with
tibia to form proximal tibiofibular joint
lateral malleolus (what form)
forms part of ankle joint
