What is the role of an exocrine gland?

to secrete substances onto body surfaces or into body cavities

Which of the following is a role of connective tissue?

transportation of bodily substances

Which of the following is NOT a type of connective tissue?

A: Transitional Blood is a connective tissue with a liquid matrix called plasma. Bone is a connective tissue with a solid matrix. Cartilage is a connective tissue that functions to cushion and support body structures. Transitional is a type of epithelial tissue that stretches readily and permits stored urine to distend a urinary organ such as the bladder.

Which of the following is a unicellular gland associated with mucus production?

Goblet cells, located between columnar epithelial cells, function in producing the protein mucin, which, when combined with water, forms mucus.

Which of the following statements about macrophages is true?

Macrophages are phagocytic cells.

Connective tissue arises from which of the following embryonic tissues?

Mesoderm gives rise to connective tissue.

Microvilli are found on the __________ surface of the epithelial cells.

Microvilli are present on the free surface of the cell, which is the apical surface.

A multicellular gland with round secretory cells and branching ducts is described as __________.

Multicellular exocrine glands with round secretory cells are alveolar, and if the ducts branch, they are considered compound.

Which of the following regulates and controls body functions?

Nervous tissue sends electrical signals to control the body.

Which of the following descriptions best describes a squamous-shaped cell?

Squamous cells are flattened and scale-like.

Which of the following types of epithelial tissue provides the greatest amount of protection from rubbing, wear, and tear?

Stratified squamous is the thickest form of epithelial tissue and is composed of multiple layers of flat cells.

Mucous that protects your stomach lining is secreted by which type of epithelial cell?

These specialized simple columnar epithelial cells are goblet cells.

Which of the following is NOT a function of areolar connective tissue?

While areolar connective tissue holds body fluids, stores nutrients, supports and binds other tissues, and defends the body against infection, movement of body parts is a task performed by the three different types of muscle tissue: skeletal, cardiac, and smooth.

A sebaceous (oil) gland of the skin must completely rupture to release its secretory products. Thus, this type of gland is considered to be __________.

a holocrine gland

The best classification of adipose tissue is __________.

a loose connective tissue

The skin is a __________ membrane.

cutaneous

white blood cells

body's defense system

chondroblasts

formation of cartilage

fibroblasts

formation of connective tissue proper

Which of the following "sets the stage" for tissue repair?

inflammation The steps in tissue repair are inflammation, organization, and regeneration.

stratified squamous

protection from wear and tear

You observe a tissue that has cells of varying heights. At first glance, it appears that the tissue has multiple cell layers, but upon closer investigation you see that all of the cells attach to the same basement membrane. What classification would you give to this epithelial tissue?

pseudostratified columnar epithelium

Neurons are cells that are involved in __________.

responding to stimuli

What type of tissue forms tendons?

A: Dense regular connective tissue regular connective tissue forms tendons.

The basement membrane is located between which of the following tissue types?

A: Epithelia and Connective Tissues Epithelial tissue secretes the superficial basal lamina region of the basement membrane, whereas connective tissue produces the deeper reticular layer of the basement membrane.

During the process of tissue repair, which of the following processes produces scar tissue?

A: Fibrosis During the process of tissue repair, fibrosis involves the proliferation of a fibrous connective tissue called scar tissue.

Embryonic ectoderm develops into which of the following major tissue types?

A: epithelial tissue and nervous tissue Nervous tissue develops solely from embryonic ectoderm, while epithelial tissues develop from ectoderm, endoderm, and mesoderm embryonic tissue.

Which of the following correctly characterizes epithelial tissue?

All epithelia have an apical surface and a lower attached basal surface and exhibit apical-basal polarity.

A flat, sheetlike tendon that connects muscle to bone is known as __________.

An aponeurosis is a flat, sheetlike tendon that connects muscle to muscle or bone.

What type of connective tissue provides support and protection for body structures and is a site for synthesizing blood and fat storage?

Because of its rocklike hardness, bone has an exceptional ability to support and protect body structures.

Which type of muscle tissue has intercalated discs and is involuntarily controlled?

Cardiac muscle is characterized by the presence of intercalated discs. Additionally, cardiac muscle is under an involuntary control mechanism.

Which cells secrete the ground substance of cartilage?

Chondroblasts secrete the ground substance of cartilage.

Which of the following statements about collagen is true?

Collagen is a fibrous protein that provides tensile strength to certain connective tissues.

The stroma of most lymphoid organs is composed of ___________.

Reticular connective tissue forms the stroma, or foundation, of most solid organs.

Which of the following tissues lines the majority of the digestive tract, from stomach to rectum?
