Chapter 8 Flashcards
what is the pectoral girdle
articulates with the trunk and supports the upper limb
what does the pectoral girdle consist of
the clavicle and scapula
what does the clavicle articulate wit
the manubrium of the sternum and laterally with the acromion
what is the scapula
a broad flat triangular bone that is located posteriorly on the body
glenoid cavity
articulates with head of humerus spin
spine of scapula
slender piece of bone on the posterir side of
acromion process
laterally to the spine
coracoid process
anterior projection
what are the parts of the upper limb
humerus, radius, ulna, carpals, metacarpals, and phalanges
parts of the proximal part of the brachium
head, anatomical neck, surgical neck, greater and lesser tubercles, and intertubercular sulcus
distal features of the brachium
shaft, deltoid tuberosity, medial and lateral epicondyles, capitulum, trochlea
distal fossae of the brachium
radial, coronoid, olecranon fossa
what is the antebrachium
the forearm, where the ulna and radius are located
parts of the radius
head of radius, neck, radial tuberosity, styloid process, ulnar notch, and carpal articular surface
parts of the ulna
trochlear notch, olecranon process, coronoid process, radial notch, head of ulna, styloid process
parts of the carpal
scaphoid, lunate, traquetral, pisiform, trapezium, trapezoid capitate, and hamate
how many metacarpals are there
5 each hand
how many proximal phalanges are there
5 each hand
how many middle phalanges are there
4 head hand
how many distal phalanges are there
5 each hand
what are the parts of the lower extremities
pelvic girdle, femur, tibia, fibula, tarsals, metatarsals, and phalanges
what are the parts of the pelvic girdle
the symphysis of two os coxae
what is the os coxae
the hip bone that is a fusion of the ilium, ischium, and pubis
what are the articulations of the os coxae
anteriorly with the os coxae, posteriorly with the sacrum, laterally with the femur at acetabulum
what is the ilum
the superior part of the os coxae
what are the parts of the ilium
ala, arcuate line, iliac fossa, anterior & posterior & inferior gluteal lines, iliac crest, anteriro & posterior superior & inferior iiac spines, greater sciatic notch, auricular surface, iliac tuberosity
ala of the ilium
wide fan-shaped portion of the posterior side of the ilium
arcuate line of the ilium
ridge along inferior border of the Ala
iliac fossa
large depression on the medial surface
anterior, posterior, and inferior gluteal lines
lateral sites of muscle attachment
iliac crest
the superior ridge of the os coxae
anterior, posterior and inferior iliac spines
projections along iliac crest
greater sciatic notch
for sciatic nerve entering lower limb
auricular surface
medial articulation with sacrum
what is the ischium
superior/posterior margin of the acetabulum
parts of the ischium
ischial spine, ischial tuberosity, ischial ramus
ischial spine
prominent medial process
ischial tuberosity
rough inferior projection that supports weight of body when seated
ischial ramus
extends from tuberosity to pubis
what is the pubis
the anterior region of os coxae
parts of the pubis
superior and inferior rami, pubic crest, obturator foramen, pectineal line
superior and inferior rami
extended between acetabulum and ischail ramus
pubic crest
rough ridge on anterosuperior of superior ramus
obturator foramen
large space boarded by pubic and ischial rami
pectineal line
ridge on medial surface of pubis contunuing from arcuate line of ilium
