BSC2085 Lesson 6 (LEC)

Most connective tissues have which of the following properties in common?

• They have cells scattered within an extracellular matrix.

• They lack any extracellular matrix.

• They are avascular and contain no fibers.

• They consist only of tightly packed cells.

The types of cells found in connective tissue include which of the following?

• Fibroblasts, macrophages, mast cells, and adipocytes

• Neurons, glial cells, and Schwann cells

• Keratinocytes, melanocytes, and Langerhans cells

• Osteocytes, chondrocytes, and myocytes

The matrix of a connective tissue is composed of which of the following components?

• Fibers and ground substance

• Nuclei and cytoplasm

• Blood vessels and nerves

• Epithelial cells and basement membrane

Which of the following best describes the classification, cellular components, and matrix of 10 types of connective tissue, and what distinguishes them from each other?

• Connective tissues are classified into loose, dense, cartilage, bone, blood, adipose, reticular, elastic, lymph, and hemopoietic; each has unique cells and matrix composition distinguishing their functions.

• Connective tissues are only classified as bone and blood, both having the same cellular components and matrix.

• All connective tissues have identical cellular components and matrix, with no distinguishing features.

• Connective tissues are classified by their location in the body, not by cellular or matrix differences.

Identify the type of connective tissue shown in the specimen or photograph.

• Adipose tissue

• Nervous tissue

• Muscle tissue

• Epithelial tissue

What is the most abundant, widely distributed, and variable type of tissue in which cells occupy less space than matrix?

• Muscle tissue

• Connective tissue

• Nervous tissue

• Epithelial tissue

Which of the following is NOT a basic characteristic of connective tissue?

• A) Specialized cells

• B) Solid extracellular protein fibers

• C) Fluid extracellular ground substance

• D) Lack of extracellular components

Fill in the blank: The ________ makes up the majority of the connective tissue volume and determines the tissue’s specialized function.

• matrix

• cell membrane

• nucleus

• cytoplasm

Which component of connective tissue fills space between cells and can slow down movement of pathogens infecting the tissue?

• Solid extracellular protein fibers

• Fluid extracellular ground substance

• Specialized cells

• Plasma membrane

Specialized cells in connective tissue mean there is only one cell type present in the tissue.

• True

• False
