BIOG221: Connective, Muscular, Nervous Tissues

Covers the connective, muscular, and nervous tissues, their function, and a possible location for each.

connective tissue (CT)

the most abundant tissue type; cells are packed loosely to allow for movement

adipose CT

provides fat storage and insulation

dense regular CT

provides strength, densely packed together containing collagen fibers; makes up the tendons and ligaments

dense irregular CT

the dermis of the skin, is less dense than its regular version, contains collagen fibers

bone CT

osteocytes, provide support; located in the skeleton

blood

transport substances, have many types (RBC, WBC, platelets, etc.); located in the heart and blood vessels

elastic cartilage

provide strength and shape, contain lacunae

fibrocartilage

allows strength and resists compression between bones

hyaline cartilage

provides flexible support

smooth muscle tissue

involved in involuntary control mechanisms; lines hollow organs

cardiac muscle tissue

striated and involuntary with a disk-like appearance; lines the heart

skeletal muscle tissue

striated and controls voluntary mechanisms; attached to the skeleton

nervous tissue

sends signals throughout the body that controls and coordinates body movements; found in the brain and spinal cord

loose areolar CT

provides support for the epithelial layers, cushions the organs; found beneath epithelial tissues
