Question 1

A type of intercellular junction that stops materials from crossing an epithelium between cells is termed an)

Accepted Answer

Occluding junctions, also known as tight junctions, prevent the passage of materials between epithelial cells by sealing the space between them.

Question 2

In stratified epithelia adapted to resist mechanical forces, which of the following types of cell- to- cell junctions are especially abundant?

Accepted Answer

Desmosomes are especially abundant in stratified epithelia that resist mechanical forces, as they provide strong adhesion between cells, helping to maintain tissue integrity under stress.

Question 3

Close examination of an organ reveals a lining of several layers of cells. The layers do not contain any blood vessels and one surface of the cells is open to the internal cavity of the organ. This tissue is probably

Accepted Answer

The description matches epithelial tissue, which is characterized by multiple layers of cells, lack of blood vessels, and an exposed surface facing an internal cavity.

Question 4

Cells that store fat are called

Accepted Answer

Adipocytes are specialized cells that store fat in the body. They are also known as fat cells and are primarily found in adipose tissue.

Question 5

The epithelia that line body cavities and blood vessels are classified as

Accepted Answer

Simple squamous epithelium is a single layer of flat cells that lines body cavities and blood vessels, allowing for efficient diffusion and filtration.

Question 6

Epithelium is connected to underlying connective tissue by

Accepted Answer

The basal lamina is a layer of extracellular matrix secreted by epithelial cells, on which the epithelium sits, and it connects the epithelium to the underlying connective tissue.

Question 7

The framework or stroma of organs such as the spleen, liver, and lymph nodes is made up of ____tissue.

Accepted Answer

The framework or stroma of organs like the spleen, liver, and lymph nodes is primarily composed of reticular connective tissue, which provides structural support.

Question 8

Satellite cells are found in association with

Accepted Answer

Satellite cells are primarily associated with skeletal muscle, where they play a crucial role in muscle growth and repair.

Question 9

Which of the following is a type of secretion in which some cytoplasm is lost with the product?

Accepted Answer

In apocrine secretion, a portion of the cell's cytoplasm is pinched off along with the secretory product.

Question 10

Adhesions of abdominopelvic organs occur when

Accepted Answer

Adhesions of abdominopelvic organs typically occur when serous membranes, which line and enclose several body cavities, are damaged.

Question 11

Osseous tissue is also called

Accepted Answer

Osseous tissue is another term for bone tissue, which is the major structural and supportive connective tissue of the body.

Question 12

Chondroitin sulfate is abundant in the matrix of

Accepted Answer

Chondroitin sulfate is a major component of cartilage, where it helps provide resistance to compression and contributes to the tissue's resilience and elasticity.

Question 13

Two types of microphages include

Accepted Answer

Neutrophils and eosinophils are both types of microphages, which are small phagocytic cells that respond quickly to infections.

Question 14

Connective tissue fibers are produced mainly by

Accepted Answer

Fibroblasts are the primary cells responsible for producing connective tissue fibers, including collagen, elastin, and reticular fibers.

Question 15

Two classes of macrophages include

Accepted Answer

Fixed macrophages reside in specific tissues, while free macrophages move throughout the body to sites of infection or injury.

Question 16

_____attach skeletal muscles to bones, and ____connect one bone to another.

Accepted Answer

Tendons attach skeletal muscles to bones, while ligaments connect one bone to another.

Question 17

Glands that secrete hormones into the interstitial fluid are

Accepted Answer

Endocrine glands secrete hormones directly into the interstitial fluid, from where they diffuse into the bloodstream.

Question 18

Which of these refers to the dense connective tissue that surrounds a muscle and blends with the tendon?

Accepted Answer

Deep fascia is the dense connective tissue that surrounds muscles and blends with tendons, providing support and structure.

Question 19

The serous membrane lining the abdominal cavity is the

Accepted Answer

The peritoneum is the serous membrane that lines the abdominal cavity.

Question 20

The dominant fiber type in dense connective tissue is

Accepted Answer

Dense connective tissue is primarily composed of collagen fibers, which provide strength and support.
