The epiphyseal plates in the _________ are the last ones in the body to ossify.

clavicle

The zones found in an epiphyseal plate are a: Calcified cartilage b: Hypertrophic cartilage c: Ossification d: Resting cartilage e: Proliferating cartilage The correct order for these zones, beginning with the edge closest to the epiphysis and proceeding toward the diaphysis, is

d-e-b-a-c

If you move your head in such a way to look up at the ceiling, you are _________ your neck.

extending

The membranous sheets that connect developing cranial bones are called

fontanelles

glenoid cavity

hinge

A synarthrosis is

immobile

The ___________ of the scapula is the point where the medial and lateral borders meet.

inferior angle

On the os coxae, the ischial ramus is fused to the

inferior pubic ramus

The _________ provide passageways for spinal nerves to exit the vertebral column and travel to other parts of the body.

intervertebral foramina

In anatomic position, the radius lies _____ to the ulna.

lateral

The movement that occurs when the trunk of the body moves in a coronal plane laterally away from the body is

lateral flexion

Interstitial growth of cartilage increases its ______ and occurs in the _______ region of the cartilage.

length; internal

A synarthrotic joint would have

low mobility and high stability.

Which bone is not paired?

mandible

The hyoid bone is located between the

mandible and the larynx.

When bone forms by intramembranous ossification, the ossification centers are within

mesenchyme

Which are not considered to be features of a synovial joint?

muscles

Osteoid is the

organic part of the bone matrix that gives it tensile strength.

Common, wear-and-tear arthritis, in which repeated use of a joint gradually wears down the articular cartilage, is known as

osteoarthritis.

As the bone matrix calcifies and the secreting cells become walled in,

osteoblasts become osteocytes.

a and c

The ligamentum teres of the hip extends from the

acetabulum to the head of the femur.

Each of the depressions on the maxillae and mandible that holds a tooth is called a(n)

alveolus.

Bone growth in which the bone increases in diameter is called

appositional growth

Gomphoses

are found only in tooth sockets.

Rami, trochanters, tubercles, and tuberosities are bone markings that serve as

attachments for ligaments or tendons.

Sutures are joints that are found

between certain bones of the skull.

The ________ joint is the simplest synovial joint and also the least mobile synovial joint

plane

f a heavy load is at one end of a lever, the distance between the fulcrum and that load is called the

resistance arm

Parathyroid hormone and calcitriol

stimulate osteoclasts to resorb bone and release calcium into the blood.
