spongy bone

composed of small needlelike pieces of bone and lots of open space

ventral body cavity

contains all the structures within the chest and abdomen

4 major sutures of the skull

coronal, sagittal, lambdoid, squamous

hallux

great toe

Which bone feature is only found on cervical vertebrae?

transverse

Which bone feature is only found on cervical vertebrae?

transverse forearm

The protein found in large amounts in the outermost layer of epidermal cells is keratin.

true

stratum granulosum

A thin layer named for the abundant granules its cells contain. These granules are (1) lamellar granules, which contain a waterproofing glycolipid that is secreted into the extracellular space; and (2) keratohyaline granules, which help to form keratin in the more superficial layers.

central canal

A tiny channel found within the spinal cord and inferior medulla oblongata

posterior cruciate ligament

Attaches to posterior tibia Prevents backward sliding of tibia and forward sliding of femur

squamous suture

Between parietal and temporal bones by ears

proximal

Closer to the origin of the body part or the point of attachment of a limb to the body trunk

dorsal body cavity

Contains the cranial cavity and the spinal cavity

How do nutrients reach the epidermis of the skin?

Diffusion transports nutrients from blood vessels in the dermis into the epidermis.

frontal plane

Divides the body into front and back portions.

Frontal bone markings

Forms the forehead, superior part of the orbit, and the floor of the anterior cranial fossa.

inorganic components of bone

Hydroxyapatites (mineral salts)

supination

Palm up

stratum lucidum

Present only in thick skin. A very thin transparent band of flattened, dead keratinocytes with indistinct boundaries.

stratum corneum

The outermost layer consisting of 20-30 layers of dead, scalelike keratinocytes. They are constantly being exfoliated and replaced by the division of the deeper cells.

Which cartilage forms the meniscus?

fibrocartilage

frontal cranial bone

forms the forehead

Patient RX has been stabbed in the anterior, medial region of the right femoral region. What is the best description to tell the patient's family where the injury was located?

front mid-region of the right thigh

antecubital

front of elbow

The ________ body plane of section divides the body into anterior and posterior parts.

frontal

head

articular cartilage

hyaline cartilage that covers ends of bones in synovial joints

3 types of cartilage

positive feedback loop

increases and reinforces initial stimulus
