The student will identify the parts of the microscope from Chapter 4. The student will know the function and how to use each part:
· eyepiece with ocular lens
· body tube
· arm
· nosepiece
· rotating nosepiece
· objective lenses
· stage
· stage (slide) clips
· mechanical stage
· mechanical stage control
· fine adjustment
· coarse adjustment
· base
· power switch
· light control
· substage light
· condenser
· iris diaphragm lever
The student will identify why a given slide is not viewable.
The student will identify the proper way to carry, use, clean and store a microscope.
The student will define:
· tissue – Identify the four categories, functions and characteristics of each
· histology
· integumentary system
The student will identify the following from the microscope and skin model:
Three layers of the integument:
v epidermis
vfive cell layers
v stratum corneum
v stratum lucidum
v stratum granulosum
v stratum spinosum
v stratum basale
v dermis
vTwo regions
v papillary region – upper 1/5th
v reticular region
v hypodermis (subcutaneous)
The student will identify the following structures from the microscope or model:
v Pacinian corpuscle (lamellated corpuscle)
v Meissner’s corpuscle
v hair root and shaft and follicle
v sebaceous gland
v arrector pili muscle
v sudoriferous gland – eccrine & apocrine
TISSUES
The student will identify the tissues and features using the microscope.
Epithelial tissue
(Epithelium)
TISSUE: SLIDE or LOCATION: FEATURES:
simple squamous epithelium lung and kidney glomerulus
stratified squamous epithelium epidermis
simple cuboidal epithelium kidney
simple columnar epithelium digestive tract
pseudostratified columnar epithelium trachea lining cilia, goblet cell
transitional epithelium bladder
Connective
Tissue
TISSUE: SLIDE or LOCATION: FEATURES:
areolar connective tissue loose connective tissue fibroblast
elastic and collagen fibers
adipose tissue adipose, hypodermis adipocyte
reticular connective tissue spleen, lymph node
elastic connective tissue aorta wall elastic fibers
dense regular connective tissue tendon fibroblast, collagen fibers
dense irregular connective tissue dermis (reticular region) fibroblast, collagen fibers
hyaline cartilage connective tissue trachea chondrocyte in lacuna
elastic cartilage connective tissue epiglottis, ear chondrocyte in lacuna
elastic fibers
fibrocartilage connective tissue intervertebral disc chondrocyte in lacuna
collagen fibers
blood connective tissue blood erythrocytes and leukocytes
bone connective tissue bone osteocyte
Muscle
Tissue
TISSUE: FEATURES:
skeletal muscle striations, multinucleated
cardiac muscle striations, intercalated disc, branched fibers, nucleus
smooth muscle nonstriated, nucleus
Nervous
Tissue
TISSUE: SLIDE or LOCATION: FEATURES:
nervous tissue brain and spinal cord neuron
NOTE:
When asked to identify the type tissue, the student must include epithelial tissue (epithelium) or connective tissue with the type tissue. Example: Simple squamous epithelial tissue or simple squamous epithelium, and dense regular connective tissue are correct; whereas, simple squamous or dense regular are incorrect.
