calcaneus talus navicular medial cuneiform intermediate cuneiform lateral cuneiform cuboid

superior surface of the head of the radius articulates with the

capitulum

carpals

forms the true wrist - proximal region of the hand

carpus

the hand includes

carpus (wrist) metacarpals (palm) phalanges (fingers)

the pectoral girdle consists of the

clavicle scapula

bounded by alae of the iliac bones

false (greater) pelvis

bony pelvis is divided into two regions

false (greater) pelvis true (lesser) pelvis

longest and strongest bone of the body

femur

the single bone of the thigh

femur

what does the tibia articulate with at it's superior end to form the knee joint

femur

the distal end of the ulna is separated from carpals by

fibrocartilage

stick-like lateral bone of the leg

fibula

which metatarsal supports body weight

first metatarsal

the pelvic girdle consists of what paired bones

hip bones (coxal bones)

longest and strongest bone of the upper limb

humerus

proximal ends of the radius and ulna articulate with the

humerus

the bone in the brachium region is the

humerus

large, flaring bone

ilium

the coxal bones consist of 3 separate bones in childhood, they are

ilium ischium pubis

what connects the tibia and fibula

interosseous membrane

what interconnects the radius and ulna

interosseous membrane

strongest part of the hip bone

ischial tuberosities

scapula's 3 angles

lateral superior inferior

in the anatomical position the radius is ____ and the ulna is ____

lateral medial

region of the lower limb between the knee and the ankle

leg

the pelvic girdle attaches to the axial skeleton by strong

ligaments

what kind of bone is the metatarsal

long bone

medial end of clavicle articulates with

manubrium first rib

how are the metatarsals named

numbered 1-5 beginning with the hallux (great toe)

how are the metacarpals and phalanges named

numbered 1-5 beginning with the pollex (thumb)

the metacarpals form the

palm

triangular sesamoid bone

patella

the appendicular skeleton consists of the

pectoral girdle pelvic girdle

attaches lower limbs to the spine

pelvic girdle

the tarsus makes up the _____ half of the foot

posterior

the pelvic girdle articulates ______ with the _____

posteriorly sacrum

except for the pollex, each finger has 3 phalanges, what are they

proximal middle distal

except for the hallux each toe has 3 phalanges, what are they

proximal middle distal

radius and ulna articulate with each other at the

proximal and distal radioulnar joints

left and right pubic bones are joined by fibrocartilage at the midline, where they connect is called the

pubic symphysis

the head of the radius articulates with the

radial notch of the ulna

contributes heavily to the wrist joint

radius

the antebrachium is formed by the

radius ulna

the humerus articulates with the ____ and ____ at the elbow

radius ulna

the scapula is located between

ribs 2-7

when the ilium articulates with the sacrum it forms

sacroiliac joint

proximal row of carpal bones from lateral to medial

scaphoid lunate triquetrum pisiform

acromial end of the clavicle articulates with the

scapula

doesn't join each other or the axial skeleton

scapula

laterally the ends of the clavicles join the

scapula

lie on the dorsal surface of the rib cage

scapula

the humerus articulates with the _____ at the shoulder

scapula

scapula's 3 borders

superior medial (vertebral) lateral (axillary)

important functions of the foot

support body weight lever to propel body segmentation makes it pliable

what does the tibia articulate with at the inferior end to form the ankle joint

talus

body weight is primarily borne by the

talus calcaneus

foot is composed of

tarsus metatarsus phalanges

region of the lower limb between the hip and the knee

thigh

more massive medial bone of the leg that receives weight of the body from the femur

tibia

the leg is composed of the

tibia fibula

distal row of carpal bones from lateral to medial

trapezium trapezoid capitate hamate

interior to the pelvic brim and forms a bowl containing the pelvic organs

true (lesser) pelvis

the carpal bones are arranged in

two irregular rows

hinge joint allows forearm to bend on arm

ulna

plays little to no role in hand movement

ulna

responsible for forming the elbow joint with the humerus

ulna

the pelvic girdle supports what organs

visceral organs
