The proximal end of the humerus features a rounded head that articulates with the glenoid cavity of the scapula to form the ___________ -.
glenohumeral (shoulder) joint
Lateral to your umbilicus, the projection you can palpate from the surface that people usually call your "hip bone" is actually what
iliac crest
When you are sitting your weight is resting on the

lateral malleolus of the fibula
Male pubic arch is _______ than 90 degrees
less
The _____________ is a small bone located anterior to the knee joint.
patella
The projection on the posterior-medial aspect of your wrist is formed by the
styloid process of the ulna
The skull begins development during
the fourth week after fertilization
Which leg bone bears the weight of the body
the tibia
The sharp line along the anterior surface of your lower leg (your shin) is formed by the anterior crest of the ________
tibia
Another name for the knee joint is the __________ joint.
tibiofemoral
The roughened section on the humerus where the deltoid muscle attaches is called the deltoid ________
tuberosity
The pectoral girdles do not articulate with the ________and are held in position and stabilized by a group of large muscles that extend from the vertebral column and _____ to the _________.
vertebral column, ribs, scapula
Which of the three basic embryonic tissues—ectoderm, mesoderm, and endoderm—gives rise to most of the skeletal system?
Most of the skeletal system arises from embryonic mesoderm.
The head of the femur fits into the ____________, a depression or socket in the hip bone.
acetabulum
The scapula articulates with the clavicle at the
acromioclavicular joint
When you palpate your shoulder, the highest point you feel is the _________ process.
acromion
Your "heel" bone is the
calcaneus
At the elbow joint, the radius articulates (connects) with the
capitulum of the humerus
Which bones make up the pectoral girdle
clavicle and scapula
How many total phalanges are in the body
56
The ______ is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the _______ joint.
Acetabulum; coxal
lists the bones forming the lower limb from proximal to distal
Femur, patella, tibia and fibula, tarsals, metatarsals, phalanges
lists the bones of the upper limb from proximal to distal
Humerus, ulna and radius, carpals, metacarpals, phalanges
Examples of Tarsals
Talus, calcaneus, navicular
What are the functions of the bony pelvis
The bony pelvis attaches the lower limbs to the axial skeleton and supports the backbone and pelvic viscera.
Which part of the hip bone articulates with the femur? with the sacrum
The femur articulates with the acetabulum of the hip bone; the sacrum articulates with the auricular surface of the hip bone.
What is the function of the pectoral girdle?
The pectoral girdles attach the upper limbs to the axial skeleton.
what bones form the bony pelvis
The pubic symphysis, the os coxae, and sacrum
T/F The measurements false and true pelves would be important to a pregnant female since the fetus must pass through the openings during birth.
True
The female's pelvis is wider and shallower than the males in order to accommodate the passage of the infant's head at birth
True
The longitudinal and transverse arches of the foot function to provide support and leverage.
True
Most skeletal tissue arises from
mesenchymal cells, connective tissue cells derived from mesoderm
