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
