(Microscope Lab) Histology Assignment Due by end of class.
Objective: Learn histological characteristics of various tissue types.
For each of the following tissues, do the following:
1. Set up the slide on the mechanical stage of the microscope.
2. Examine the slide at low, medium and high magnifications
3. Scan the slide to find a portion comparable to the photograph found in the
textbook. You may need to increase or decrease the magnification.
4. On separate paper, draw & label each tissue type (2-4 illustrations per page).
a. Draw what you see through the microscope, using textbook
illustrations/iPad as guidelines.
Tissues to draw:
1) SIMPLE COLUMNAR EPITHELIUM
Label: basement membrane (basal lamina), cell nucleus, cytoplasm, cell
membrane, free (apical) surface
2) SKIN: STRATIFIED SQUAMOUS EPITHELIUM
Label: basement membrane (basal lamina), strata (layers), cell nucleus,
cytoplasm, cell membrane, free (apical) surface, hair follicle (if present)
3) SIMPLE CUBOIDAL EPITHELIUM (use Kidney section)
Label: basement membrane, cell nucleus, cytoplasm, cell membrane, free
surface
4) HYALINE CARTILAGE (use TRACHEA section)
Label: extracellular matrix, chondrocyte, lacuna, perichondrium
5) GROUND BONE (use cross-sections, usually indicated by X or XS, on the slide
label. Do not use developing bone or metaphysis slides)
Label: extracellular matrix, osteocyte, lacuna, canaliculi, haversian canal
(central canal), osteon
6) BLOOD SMEAR
Label: red blood cell (erythrocyte), white blood cell (leukocyte), platelet
(thrombocyte)
7) SKELETAL MUSCLE
Label: individual skeletal muscle cell, nuclei, striations, cytoplasm, sarcolemma
(cell membrane)
8) CARDIAC MUSCLE (use longitudinal sections)
Label: nuclei, striations, cytoplasm, intercalated disks
9) NEURON (use either SPINAL CORD or GIANT MOTOR NEURON sections)
Label: nucleus, cytoplasm, axon, dendrite
10) SIMPLE SQUAMOUS
11) **EXTRA SLIDE (each group is different: lung, cornea, stomach, etc.)
