web site http://www.med.umich.edu/histology/dmindex.html
Lab Activity 2 - Bone Ground Page 210
University of Michigan support for this Lab Activity.
Ground section of compact bone,
cross, 40X. This slide is
similar to Fig. 10.14 in workbook. Identify the following structures on
this slide: osteon=Haversian system, osteocytes, Haversian
(central) canal, canaliculi, matrix, lamellae). |

Ground section of compact bone,
cross, 40X This
slide is similar to Fig. 10.14 in
workbook. Identify the following structures on
this slide: osteon=Haversian system, osteocytes,
Haversian (central) canal, canaliculi, matrix, lamellae). |
|||
Ground section of compact bone, longitudinal
section, 40X (thin section). Identify the following structures on
this slide: osteon=Haversian system, osteocytes,
Haversian (central) canal, canaliculi, matrix, lamellae). |

Lab Activity 3 - Bone Demineralized Page 211
University of Michigan support for this
Lab Activity. This
slide is a cross section of a long bone with surrounding cross-sectioned
skeletal muscle with tendon. This slide
shows several sites of Periosteum to
Tendon Junctions (see Workbook Lab Activity 12, slide is similar to Figure 10.16, page 221 and in the Worksheets page 115, Fig. 8.24).
|
Decalcified bone, cross section, H&E,
20X Identify
the following structures on this slide: osteon=Haversian system, osteocytes,
Haversian (central) canal, collagen fibers, lamellae, periosteum, endosteum,
bone marrow, blood vessels in bone marrow).

Lab Activity 4 – Intramembranous
Ossification Page 214
University of Michigan support for this
Lab Activity.
Observe the palate for structure of intramembranous ossification.
Palate, saggital
section, H&E, 40X. This slide is
similar to Figures 10.23 and 10.24
of workbook. Identify region of palate showing intramembranous
bone formation. Identify fibrous membrane, region of spongy
bone (look for trabeculae), region of compact bone (look for a group of osteons
in cross-section), periosteum, endosteum, osteocytes,
osteoblasts, newly forming osteons, blood vessels, collagen
fibers of the bone. |
|||
Fetal face and jaw, frontal
section, H&E, 40X Identify
region showing intramembranous bone formation. Identify fibrous membrane, region of spongy
bone (look for trabeculae), periosteum, osteocytes, osteoblasts, blood vessels, collagen fibers
of bone. Is this slide
development younger or older than the above slide preparation? |
Lab Activity 7 – Endochondrial
Ossification Page 216
University of Michigan support for this
Lab Activity. This
slide is a longitudinal section of a long bone (finger) with the middle phalanx
similar to Fig. 10.34 of workbook).
Finger, H&E, 20X Why
is this an example of endochondral bone
formation? Identify proximal and
distal epiphyses, proximal and distal metaphyses,
diaphysis, hyaline cartilage (region of articulation, region of
proliferation, region of hypertrophy, and region of cavitations), trabeculae,
fibrous and cellular layers of periosteum, osteons (forming and developed),
endosteum, osteoblasts, osteocytes, compact bone,
medullary cavity (forming), bone marrow, dense connective tissue of joint. |
Lab Activity 9 – Endochondrial
Ossification Page 219
University of Michigan support for this
Lab Activity. This
slide is a longitudinal section of a long bone similar to Fig. 10.40 of workbook).
Developing long bone, H&E, 20X
Identify
epiphyses, metaphyses, diaphysis, hyaline cartilage
(region of articulation, region of proliferation, region of hypertrophy, and
region of cavitations), trabeculae, fibrous and cellular layers of
periosteum, osteons (forming and developed), endosteum, osteoblasts, osteocytes, compact bone, medullary cavity (forming),
bone marrow. Does this slide show a secondary ossification center? Does this
slide show appositional growth? |
Lab Activity 12 – Decalcified Bone
showing Appositional Growth Page 221
University of Michigan support for this
Lab Activity.
Fetal leg,
cross section, H&E, 40X. This
slide is similar to Figure 10.46 and
10.47 of workbook.) |
|||
Identify
spongy bone, trabeculae, fibrous and cellular layers of periosteum, tendon to
periosteum junctions, osteons (forming and developed), endosteum,
osteoblasts, osteocytes, compact bone, medullary
cavity (forming), bone marrow. Does this slide show longitudinal growth? |
|||
Decalcified bone, cross section,
H&E, 20X (compact bone, osteon=Haversian system). This slide is similar
to Figure 10.46 and 10.47 of
workbook.) |
|||
|
Identify
compact bone, fibrous and cellular layers of periosteum, tendon to periosteum
junctions, osteons (forming and developed), endosteum, osteoblasts, osteocytes, medullary cavity, bone
marrow. Does this slide show
longitudinal growth? Is the bone development
of this slide older or younger than the prior (above) slide? |

Lab Activity 13 – Thyroid and
Parathyroid Glands Page 222
University of Michigan support for this
Lab Activity. This
slide is mostly thyroid gland. The
parathyroid is on small area at the bottom right as you view the slide.
This slide is similar to Figure 10.50 of workbook.
Thyroid gland and parathyroid,
H&E, 40X Identify
thyroid, follicles, follicular epithelial cells, colloid, parathyroid
(at lower right). Know stimulus, function, and target of hormones. |
Lab Activity 14 – Ground Bone showing
Remodeling Page 224
University of Michigan support for this
Lab Activity. This
slide is the same that was presented in Lab Activity 2, page 210.
Observe the slide for remodeling which is
similar to Figure 10.53 of workbook.
Ground section of compact bone,
cross, 40X Identify
osteon=Haversian system, osteocytes, canaliculi, interstitial
lamellae. Why are central canals on left side (as you view the image) a
different size than those on the right side? |
