The house mite, Dermatophagoides, feeds on dandruff which is composed of

keratin and oil.

A structurally classified joint which has no synovial cavity and is held together by ligaments is termed

fibrous

Which of these is not part of the embryonic stage of development?

differentiation of organs

The pubic symphysis is made up of

fibrocartilage.

All new epidermal cells arise from

the stratum basale.

The shoulder is a good example of a hinge joint.

False

A loss of bone mass, especially spongy bone, is usually a result of lack of exercise or deficiency of estrogen after menopause. This disorder is called

osteoporosis.

The skeleton, most muscles, dermis, blood, and blood vessels arise from

mesoderm

Glands that produce a thick, sticky secretion are called ___ glands.

mucous

A tissue specialized for energy storage and thermal insulation is

adipose tissue.

Elastic cartilage is found in intervertebral discs.

False

The germ layer that gives rise to mucous membranes of the digestive and respiratory tracts is called

endoderm.

In the zone of bone deposition, _____ cells rapidly invade the calcified matrix and lay down bone. Then ______ cells erode the spongy bone to form the marrow cavity.

osteoblast; osteoclast

The shape of a person's external ear is due mainly to

elastic cartilage.

This cell is large and flat and produces the fibers and ground substance of connective tissue.

fibroblast

The epithelium lining the trachea is capable of

producing mucus and moving material across its surface

A synchondrosis and symphysis differ only with respect to what type of cartilage joins adjacent bones to each other.

True

Simple cuboidal epithelium is found in _____ and its function is _____.

kidney tubules; absorption

The internal lining of the esophagus and adult vagina is

a stratified squamous epithelium.

The only type of cell seen in a tendon is

fibroblasts.

Hyaline cartilage is found in

costal cartilage.

Tendons and ligaments, not just bones, are considered part of the skeletal system.

True

Endochondral ossification is the development of a bone from a cartilage model.

True

Most of the space within a cell is filled with interstitial fluid.

False

The hyaline costal cartilage that attaches a rib to the sternum forms

a synchondrosis.

The embryonic disc, when first formed, has no mesoderm.

True

The cells primarily responsible for the breakdown of bone are

osteoclasts.

After a cartilage cell becomes trapped in a lacuna, it is called a chondrocyte.

True

Bones of the skull and clavicle develop by

intramembranous ossification.

This part of a synovial joint encloses the cavity, retains the synovial fluid, and is continuous with the periosteum.

fibrous capsule

During wound healing, macrophages serve to

phagocytize foreign material and the blood clot.

The joint between the ribs and costal cartilage is a ______ joint which is specifically called a ______.

cartilaginous; synchondrosis

Shiny hair gets its sheen from oil produced by the ___ glands.

sebaceous

Most bones develop from

hyaline cartilage.

Which of these is a gliding joint?

the patellofemoral joint

Which one of the following is not made of hyaline cartilage?

intervertebral disc

In a connective tissue, the extracellular matrix occupies more space than the cells do.

True

The fastest rate of mitosis is seen in

the stratum basale.

The protein fibers of the bone matrix are composed of

collagen.

The color of the skin in different races is primarily caused by the

amount of melanin formed.

The skin does not include

the hypodermis.

The epithelium of the epidermis is best described as

keratinized stratified squamous.

A fibrous joint cannot also be

a diarthrosis.

The contraction of the piloerector muscles (arrector pili) in humans causes

hairs to stand on end with no apparent function.

Which of the following tissues is found in the dermis of the skin?

dense irregular

Which one of the following does not have an abundance of collagen fibers?

cartilage of the external ear

In the blastocyst, the trophoblast will become _____, and the embryoblast will become _____.

part of the placenta; the embryo

Which one of the following bone cells would have the greatest number of lysosomes?

osteoclasts

The periosteum is a connective tissue sheath which lines the _____ of bones

outer surface

This tissue regulates what enters and what leaves the body.

epithelial

The epidermis, nervous system, pituitary, internal and external ear are derived from

ectoderm.

Nerves and blood vessels travel through compact bone.

True

Men are susceptible to osteoporosis.

True

Tendons and ligaments are made predominantly of the protein

collagen.

This layer contains areolar and adipose connective tissue, has a tendency to store fat, and is an area where drugs are commonly injected because of its high vascularity.

hypodermis

A structurally classified joint which has no synovial cavity and is held together by ligaments is termed

fibrous.

Which one of the following does not have an abundance of collagen fibers?

cartilage of the external ear

Stretch marks result from

torn collagen fibers.

In thick skin, the layers of the epidermis from deep to superficial, respectively, are the stratum

basale, spinosum, granulosum, lucidum, and corneum.

Which of these arises from the embryonic endoderm?

the digestive mucosa

humerus

formed by endochondral ossification.

The epithelia of the digestive tract, respiratory tract, urinary bladder, and accessory reproductive and digestive system glands are derived from

endoderm.

Intervertebral discs form cartilagenous joints between the vertebrae.

True

What type of joint is the epiphyseal plate?

synchondrosis

Children have more bones than adults do

True

As bone grows in the child only two areas of cartilage are left at each epiphysis. These two areas are

articular cartilage and epiphyseal plate.

Which of these lists the stages of prenatal development in correct order?

zygote, cleavage, morula, blastocyst, embryo, fetus

The nonliving material surrounding cells is called

matrix.

Which one of the below has no ducts and produces hormones?

endocrine gland

The ground substance of blood is called

plasma.

___ are single mucus-secreting cells found in the epithelia of many mucous membranes.

Goblet cells
