BIOL 231, Human Anatomy Wennstrom

Human Tissues Goals: • Identify the specific types of epithelium and connective tissue listed below through the microscope or in photographs • Identify the basement membrane of epithelia (note: the membrane is not always thick enough to be clearly visible, but its location between the epithelium and underlying connective tissue can nearly always be located). • Identify any cell types or specialized structures listed in the “Additional structures” column below through the microscope or in photographs. • Identify basic subcellular organelles when visible through the microscope (cytoplasm, nucleus, nucleolus).

Integumentary system Goals: • Identify at least two specific examples of epithelial tissues and two specific examples of connective tissues present in the skin (see slides 3 and 9). • Identify the three major layers of the skin through the microscope, on models, or in photographs: epidermis, dermis, hypodermis • Identify the four layers of the epidermis in thin skin through the microscope, on models, or in photographs: stratum corneum, stratum granulosum, stratum spinosum, stratum basale • Identify the major accessory organs of the integumentary system through the microscope, on models, or in photographs: sweat (sudoriferous) gland, sebaceous (oil) gland, hair follicle, arrector pili muscle
