Which part of the neuron (a specialized nerve cell) receives signals from other cells and is also the main metabolic region of the neuron? a) soma b) dendrites c) axon

a) soma (receives inputs (signals) from other cells and sends the information to the axon. But unlike a dendrite, it also is the main metabolic and nutritional center of the cell)

b) synovial membrane

All of the following are true of neurons except that a) they are composed of a cell body and axon b) they are a very specialized form of connective tissue c) they receive information from other neurons through their dendrites d) they cannot divide.they conduct a nervous impulse

b) they are a very specialized form of connective tissue

What type of epithelial tissue is specialized to stretch repeatedly without damage? a) stratified squamous epithelium b) transitional epithelium c) simple squamous epithelium d) simple cuboidal epithelium

b) transitional epithelium

Which muscle cell type has visible striations but is not under voluntary control? a) smooth b) skeletal c) cardiac

c) cardiac

The viscous component of connective tissue matrix is called a) collagen b) basal layer c) ground substance d) plasma e) lymph

c) ground substance

The combination of fibers and ground substance in supporting connective tissues is known as a) collagen b) cartilage c) matrix d) chondroitin e) scaffold.

c) matrix

The proximal tubule of the nephron (kidney tubule) in the kidney is composed of which type of epithelium? a) stratified squamous epithelium b) ciliated pseudostratified columnar epithelium c) simple cuboidal epithelium

c) simple cuboidal epithelium (simple cuboidal cells line the kidney tubules (nephrons) so that secretion and absorption can take place)

The wall of the alveolus (air sac) in the lung is composed of which type of epithelium? a) transitional epithelium b) simple columnar epithelium c) simple squamous epithelium

c) simple squamous epithelium (single layer of squamous cells is ideal for the diffusion of gases in the lungs)

Which of the three muscle cell types has multiple nuclei? a) smooth b) cardiac c) skeletal

c) skeletal (elongated and many can be quite long; therefore, they have multiple nuclei)

The muscle found in the walls of most hollow organs of the body is a) involuntary striated muscle b) voluntary striated muscle c) smooth muscle d) cardiac muscle e) skeletal muscle

c) smooth muscle

The epithelium of the esophagus is composed of which type of epithelial tissue? a) simple columnar epithelium b) keratinized stratified squamous epithelium c) stratified squamous epithelium

c) stratified squamous epithelium (protects underlying tissues from the wear and tear of constant swallowing in the esophagus)
