Exam 5: Tissues

A Schwann cell is a structure that is attached to a neuron and is crucial to its function. It assists in the neuron's function by speeding up the rate of signal transduction. Schwann cells are neuroglia.

Bone cells (osteocytes)are in concentric circles around central canals. 

Cartilage tissues are likely to be slow in healing following an injury because

Serous and mucous membranes consist of epithelial and connective tissues.

The band between cardiac muscle cells is called a(n)________ ________.

Spicy foods irritate the membrane of your mouth, which triggers goblet cells to produce a protective layer of a thick substance called mucus. What membrane must be lining the mouth?

What do intercellular junctions connect?

Bone cells form concentric circles around longitudinal tubes called

A mucus-secreting goblet cell is a unicellular gland.

Sickle cell anemia is a disease that causes red blood cells to become crescent-shaped and become lodged in capillaries. This disease directly affects a connective tissue.

The most abundant cells in dense connective tissue are ________.

Epithelial membranes are typically composed of

Cartilage cells occupy small chambers called ________.

The greater omentum is a structure that exists in the abdomen and hangs over the digestive tract, behind the abdominal muscles. A cross section viewed under a microscope reveals that it contains a connective tissue composed of large cells, or droplets. The cell walls are very thin and there is no collagen. The tissue looks like it might be good for cushioning. What type of connective tissue is this?

A ________ membrane lines tubes and cavities that open to the outside of the body.

The pituitary gland is a structure in the brain that secretes hormones into the bloodstream. What epithelium lines this structure and produces the secretion?

Tissues are groups of cells that have a common overall function, yet are distinctive in their characteristic cell types and the molecules that the cells produce.

What type of cell produces connective tissue fibers?

All tissue types are tightly packed, built of cells attached by intercellular junctions.

The epidermis (outer layer of the skin)needs to be tough and resistant to shearing and stretching. The type of intercellular junction best suited for this need is a(n)________.
