Which slide of skin belongs to the soles of your feet?
Its primary functions are to protect the body from the environment and prevent water loss. Skin is classified into two types: Thick skin – covers the palms of the hands and the soles of the feet. Thin skin – covers the rest of the body.
What are the characteristics of thin skin?
Thin skin definition The epidermis of thin skin ranges from 0.07–0.15 millimeters (mm). Thin skin can vary in thickness in different parts of the body and is particularly thin across the eyelids. Thin skin is thickest on the upper back. Thin skin also contains hair follicles, sweat glands, and sebaceous glands.
How do you identify histology slides?
Inspection: Inspect the slide using just your eyes and a good light source to first determine the shape of the prepared section. Occasionally, a specific section has a characteristic shape and is much easier to identify. e.g on the cross section of tracheal cartilage an annular preparation can be seen.
How thick is the dermal layer?
1 to 4 mm
Dermis and Subcutaneous Fat The dermis is a tough but elastic support structure that houses nerves, blood vessels, lymphatics, and cutaneous appendages (pilosebaceous units, eccrine and apocrine sweat glands). It is thicker (averages 1 to 4 mm) than the epidermis which is about as thin as piece of paper.
What are dermal layers?
Introduction. The dermis is a connective tissue layer sandwiched between the epidermis and subcutaneous tissue. The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands.
What types of microscope slides are used on a compound microscope?
You will be using two main types of slides, 1) the common flat glass slide, and 2) the depression or well slides. Well slides have a small well, or indentation, in the center to hold a drop of water or liquid substance. They are more expensive and usually used without a cover slip.
How thick is dermis?
The dermis is a tough but elastic support structure that houses nerves, blood vessels, lymphatics, and cutaneous appendages (pilosebaceous units, eccrine and apocrine sweat glands). It is thicker (averages 1 to 4 mm) than the epidermis which is about as thin as piece of paper.
How should you study a histological slide?
How to examine histology slides
- Inspection: Inspect the slide using just your eyes and a good light source to first determine the shape of the prepared section.
- Calibration: Place the slide under the microscope and calibrate the microscope so that the image produced is clear.
How do you identify epithelial tissue types by looking?
Epithelial tissues are classified according to the shape of the cells and number of the cell layers formed ((Figure)). Cell shapes can be squamous (flattened and thin), cuboidal (boxy, as wide as it is tall), or columnar (rectangular, taller than it is wide).
What Colour is the dermis?
Melanoid: It resembles melanin but is present diffusely throughout the epidermis. Carotene: This pigment is yellow to orange in colour. It is present in the stratum corneum and fat cells of dermis and superficial fascia….Skin colour.
V | Moderate constitutional pigmentation | Brown |
VI | Marked constitutional pigmentation | Black |
What are microscope slides made of?
Some high-quality plastics are also used to make slides, but traditionally our slides are made from high-quality glass. Since microscope slides can be used repeatedly as long as you wash and dry them carefully and completely, these are an investment you can use for years to come if you invest a set of blank slides.
What are pre-prepared microscope slides?
Prepared microscope slides are all mounted on good quality glass microscope slides with sealed cover slips to ensure longevity. They include Animal, Plant, Fungi, Protista and Monera tissue culture specimens in boxes of 5pcs, 15pcs and 50pcs.
How to choose the right microscope slides?
Choose from a professionally selected range of good quality prepared microscope slides, blank slides and stains. Prepared microscope slides are all mounted on good quality glass microscope slides with sealed cover slips to ensure longevity.
What is the packaging of the micro slides?
Each selection of micro slides is contained in a hard plastic box which offers better quality and is longer lasting than cheap wooden cases.
