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
