BIO210 Objectives for Lab Quiz #2
MICROSCOPE, TISSUES, & INTEGUMENT
The student will identify the parts of the microscope from Lab Exercise I-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 and characteristics of each
histology
integumentary system
The student will identify the tissues as given on the TISSUES list.
The student will identify the following from the microscope and skin model:
Three layers of the integument:
epidermis
five cell layers
stratum corneum
stratum lucidum
stratum granulosum
stratum spinosum
stratum basale
dermis
Two regions
th
papillary region – upper 1/5
reticular region
hypodermis (subcutaneous)
The student will identify the following structures from the microscope or model:
Pacinian corpuscle (lamellated corpuscle)
Meissner’s corpuscle
hair root and shaft and follicle
sebaceous gland
arrector pili muscle
sudoriferous gland – eccrine & apocrine
TISSUES
The student will identify the tissues and features using the microscope – Lab exercise I-5.
Epithelial Tissues (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 Tissues
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
MuscleTissues
TISSUE: FEATURES:
skeletal muscle striations, multinucleated
cardiac muscle striations, intercalated disc, branched fibers, nucleus
smooth muscle nonstriated, nucleus
Nervous Tissues
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.
