the primary function(s) of hyaline cartilage.

Multiple types of fibers running in different directions Multiple cell types are present Fibers create an observable woven or web-type pattern

visible characteristics of areolar connective tissue

Fibers create a woven or web-type pattern observable on the slide. Fibroblast nuclei are visible in a sporadic arrangement. Collagen fibers running in different directions

visible characteristics of dense irreqular connective tissue

Collagen fibers or elastic fibers running in the same direction. Fibroblast nuclei are visible, sporadically located between fibers. Very little ground substance and few cells are observable on the slide.

visible characteristics of dense regular connective tissue

There are so many layers of cells that it would be difficult to count them precisely. Stratified squamous epithelium is always adjacent to a free space or lumen. The squamous cells closer to the lumen are flatter while the squamous cells closer to the connective tissue are fuller and rounder.

Digital region

Blood calcium levels are maintained by a negative feedback homeostatic mechanism. When blood calcium levels rise beyond their set point, a hormone called calcitonin is released by the thyroid gland to lower blood calcium levels back to their set point. What role does the thyroid gland play in this mechanism?
