Lower Extremity - AP

in the normal adult, the angle formed by the neck and shaft of the femur is about

120 degrees

The total number of phalanges in the normal adult foot is

14

the head of the femur articulates with a cupshaped socket on the lateral surface of the pelvis called the

acetabulum

the navicular (scaphoid) bone of the foot is located: 1. anterior to the talus 2. posterior to the cuneiforms 3. superior to the cuboid

anterior to the talus and posterior to the cuneiforms

what type of joint is the hip

ball and socket

the cuneiform bones articulate anteriorly with the

base of the metatarsals

the cuboid bone of the foot articulates posteriorly with the

calcaneus

the largest bone in the normal adult foot is called the

calcaneus

what type of joint is the pubic symphysis

cartilaginous

what type of joint is the metatarsophalangeal joint

condylar

the large, smooth articulating surfaces located on the distal femur are termed the

femoral condyles

the smooth, upper surfaces of the proximal tibia (plateau) serves as the articulating surface for the

femoral condyles

the largest and strongest bone of the appendicular skeletal system is the

femur

the knee joint is formed by the articulation of the ___ bones

femur and tibia

what type of joint is the inferior tibiofibular joint

fibrous

the protuberance that is felt on the lateral surface of the lower leg distal to the knee joint is the

fibular head

what type of joint is the femoral patellar

gliding

what type of joint is the intertarsal

gliding

what type of joint is the sacroiliac

gliding

what type of joint is the superior tibiofibular joint

gliding

what type of joint is the tarsometatarsal

gliding

the large body ridges of the proximal femur that serve to attach many of the muscles for moving of the hip are called the

greater and lesser trochanters

the deep notch located on the posterior margin of the innominate bone between the posterior inferior iliac spine and the ischial spine is called the

greater sciatic notch

what type of joint is the ankle

hinge

what type of joint is the interphalangeal joint

hinge

what type of joint is the knee

hinge

the majority of the greater or false pelvis is formed by all or part of the

ilium

during development, the pelvis consists of 6 separate bones that fuse during childhood. These paired bones are the

ilium, ischium, pubis

the acetabulum is composed by part of the

ilium, ischium, pubis

the two large bones that help to form the majority of the adult pelvis are termed the

innominate bones

the rounded condyles of the femur are separated by a deep depression termed the

intercondylar fossa

the most superior portion of the tibia (tibial eminence) projects upwards from the plateau into the

intercondylar space

in the normal sitting position, most of the weight of the trunk is supported by the ___ of the pelvis

ischial tuberosity

the obturator foramen of the pelvis is formed by the junction of the following bones: 1. ilium 2. ischium 3. pubis

ischium and pubis

the pointed, bony prominence located on the distal fibula is called the

lateral malleolus

located on the posterior surface of the femur is a prominent ridge of bone serving for the attachment of many of the muscles of the lower extremity. This process is called the

linea aspera

fallen arches (flat feet) is often due to weakening of the ligaments in the feet and results in the loss of the ___ arch

longitudinal

the expanded portion of the proximal end of the fibula (fibular head) articulates with the tibia at the

proximal lateral surface

the two small, rounded bones that are found on the plantar surface of the first metatarsophalangeal joint to help reduce friction are termed

sesamoid bones

the astragulus (talus) bone of the foot is normally located ___ to the calcaneus (os calsis)

superior

the base of the patella is found on the ___ surface of the bone

superior

the junction of the two innominate bones at the anteroinferior margin is termed the

symphysis pubis

the ankle joint is formed by all or part of the: 1. talus bone 2. tibia 3. fibula

talus bone, tibia, and fibula

the larger and more medial bone of the lower leg is the

tibia

the tendon of the quadraceps femoris attaches on the anterior surface of a raised process of the proximal tibia called the

tibial tuberosity

when compared to the male pelvis, the female pelvis is characterized by a

wider transverse diameter larger pelvic outlet larger pubic arch
