Chapter 4 Lecture Quiz

The walls of capillaries are exceptionally thin, and this structure promotes efficient diffusion of nutrients and wastes between the bloodstream and surrounding tissue cells. The epithelium of capillary walls are:

• simple columnar

• simple squamous

• pseudostratified columnar

• stratified squamous

• simple cuboidal

In most connective tissues, the primary cell type produces the extracellular matrix. In blood:

• fibroblasts produce the extracellular matrix (plasma)

• osteoblasts secrete the extracellular matrix (plasma)

• chondroblasts secrete the extracellular matrix (plasma)

• erythroblasts produce the extracellular matrix (plasma)

• the cells do not produce the extracellular matrix (plasma)

The cutaneous membrane consists of both outer epithelium (the epidermis) and inner connective tissue (the dermis). The much-abraded, protective epidermis is made of _______ and the dermis, which can resist tension from different directions, is made of _______.

• stratified squamous epithelium, dense irregular connective tissue

• simple cuboidal epithelium, loose connective tissue

• pseudostratified columnar epithelium, elastic connective tissue

• simple squamous epithelium, reticular connective tissue

• stratified squamous epithelium, reticular connective tissue

Why is muscle tissue referred to as composite tissue?

• muscle tissue rebuilds itself after being broken down during physical exertion

• the long, cylindrical cells of muscle tissue are multinucleate (contain multiple nuclei)

• there are different types of muscle tissue (skeletal, cardiac, smooth)

• muscle tissue contains both actin and myosin in abundance

• muscle tissue is highly vascularized and therefore contains small amounts of areolar connective tissue, since all blood vessels are surrounded by this type of connective tissue

The part of the neuron that transmits signals toward the cell body is the ________, while the part of the neuron that transmits signals away from the cell body is the ________.

• dendrite, axon

• axon, dendrite

• soma, axon

• axon, soma

• dendrite, neuroglia
