Lab Exercise 7: Integumentary System
I. Lab Objectives
A. View, draw, and label a microscope slide of skin tissue
B. Observe a model of the skin and name its structures
Activity 1: Locating Structures on a Skin Model – identify the following structures on the
skin model (see picture on next page) and answer the questions below.
-Epidermis layers (from superficial to deep)
Tissue type?
Stratum corneum
Type of cells?
Function?
Stratum lucidum
Type of cells?
Only found where?
Stratum granulosum
Type of cells?
What do they produce?
Stratum spinosum
Type of cells?
What protective cells are found in this layer?
Stratum basale
3 types of cells?
What processes occur here?
Dermis layers
Papillary layer
Type of tissue?
Sensory cell type found here?
Reticular layer
Main tissue type?
2 gland types?
Pressure receptor type?
Blood vessels present or absent?
Hair follicles & arrector pili present or absent?
Hypodermis (subcutaneous tissue under the skin)
2 tissue types:
Blood vessels present or absent?
Activity 2: Identifying nail structure - Do this
Activities 3 & 4: Microscope slide of hairy skin – view the skin microscope slide provided
and be able to identify the following structures.
Epidermis
Dermis
Hair follicles, hair root, sebaceous gland, sweat gland
Hypodermis
