What is the correct order for the layers of epidermis from outermost to deep?
Stratum basale, stratum spinosum, stratum granulosum,stratum lucidum & stratum corneum
What modification of the choroid that is not present in humans is found in cow eye and what is its function?
The pigmented choroid coat is iridescent because of the tapetum lucidium and its function is that it reflects the light in the eyes and is found only in animal eyes because of low light intensity
What modification of the choroid that controls the shape crystalline lens that is not present in humans is found in cow's eyes?
I believe the answer is tapetum lucidium. It is a specialized surface that reflects the light within the eye and is found in the eyes of animals that live under conditions of low-intensity light. It's not found in humans.
In what order a needle pierce the epidermal layers of forearm?
A needle would pierce the skin from the outside inward: A layer of flat cells called as Stratum corneum, then a layer of almost transparent cells called Stratum Lucidium, then a layer of cells which look granular and is called the Stratum granulosum, next is a layer of cells called the Stratum Spinosum and lastly, a single cell layer with a prominent nucleus in each cell called the Stratum basale (the growing layer).
Do Frogs sleep at night?
Yes. Many frogs are nocturnal so have good night vision. They have a mirror layer in the back of the eye (called tapetum lucidium) that lets them reflect light at night,known as 'eye-shine'. This gives them a kind or search light for hunting by. Deferent species have different sensitivity to light depending on their habits and habitats. This can be determined by the numbers of 'rods' and 'cones' on the frogs retina (back of the eye). Rods are sensitive to light and cones detect colour.
What are the names of 3 layers of skin?
First answerThe epidermus, the dermus, and the hypodermus Another answerThe skin is composed of only two layers; the epidermis and the dermis. Though the hypodermis is often mentioned when discussing the skin, it is not actual a part of skin, but the underlying structure that supports it.
Why do animals eyes shine in the dark?
Some animal's eyes shine in the dark because of the presence of the tapetum lucidum* in the choroid layer (the middle layer) of the eye. This layer helps to reflect light, presumably allowing them to see better in the dark. This is why most animals which could be considered nocturnal have noticeably shinier eyes than, for example, humans, who do not have any evidence of the tapetum lucidum* in their choroid layer.*Please note; I'm not entirely sure about the spelling of tapetum lucidum. It could be spelled tapetum lucidium, tapetum ludicium, or any other variant, so don't go strictly by this answer! Most dictionaries have just tapetum.
What is the thicker depper layer of the skin?
The type of skin cancer which is most invasive, not only to the deepest layers of the skin, but to distant metastatic sites beyond, is malignant melanoma.
What are the layers of the skin?
The layers of the skin are the dermis, epidermis, and hypodermis. Epidermis, dermis, subcutaneous (fat)Not all professions recognize the subcutaneous as a layerThe epidermis, the dermis, and the fatty region. The epidermis is the outermost and thinnest layer. The dermis is below the epidermis and has muscles, nerve cells and blood vessels. The fatty region swells up when you gain weight. I hope this helped anyone.The epidermis is divided into several layers where cells are formed through mitosis at the innermost layers. They move up the strata, changing shape and composition as they differentiate and become filled with keratin. They eventually reach the top layer, called the stratum corneum, consisting of approximately 15-350 layers of dead cells strengthened and made water-resistant by the keratin.So right there we've got anywhere from 15-350 layers in the epidermis alone.Assuming you meant the outer skin, anywhere from 15-350 layers would be correct, depending on various factors. However, that still has tons of layers of the dermis and hypodermis underneath it.We just arbitrarily divide these sets of layers into 3 "layers".The epidermis has five layers; strautm germinativum (or basal layer), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.1. stratum corneum2. stratum lucidum3. stratum granulosum4. stratum spinosum5. stratum germinativum6. dermisIt's actually 5 layers. Starting from the top is the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and lastly stratum germinativum.Stratum corneum Stratum licidum Stratum granulosum Stratum spinosum Stratum basale Papillary Layer Reticular Layer1. Epidermis is the most superficial layer of the skin and rests on the dermis. It consists of 5 epithelial tissue layers, Which are Stratum Corneum, Stratum Lucidum, Stratum Granulosum, Stratum Spinosum, and Stratum Basale.2. Dermis, which is a layer of connective tissue, is responsible for structural strength and flexibility of the skin. It has two layers, which are Papillary Layer, and Reticular Layer.3. Subcutaneous Tissue is the third, but not actually part of the skin. It is Loose Connective Tissue that attaches the dermis to underlying structures.The three layers of human skin are:EpidermisDermisSubcutaneous tissueThe epidermis is the outer/visible layer. The epidermis consists of 5 layers in itself. From top to bottom these layers are: stratum corneum, stratum licidum, stratum granulosum, stratum spinosum, and on bottom, stratum basale.The dermis is made up of three types of tissue (throughout, not in layers): collagen, elastic tissue, and reticular fibers. The two layers of the dermis are the papillary and reticular layers.The subcutaneous tissue is a layer of fat and connective tissue in which there are larger blood vessels and nerves. This layer regulates the temperature of both the body and the skin itself.In descending order from the surface: ?epidermis, dermis and hypodermis.stratum Basalestratum Spinosumstratum Granulosumstratum Licidumstratum Corneumthe order is from bottom layer to top. you can remember the order with the acronym of, Can Lucy Give Some BloodSkin has three layers: epidermis, dermis and sub-cutaneous connective tissue. The epidermis is made of 5 stratums.Bottom to top:stratum basalestratum spinosumstratum granulosumstratum licidumstratum corneumThere are actually two main layers of skin, the dermis and the epidermis.The epidermis consists of five sublayers: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidium, and stratum corneum.There are not three layers to the skin there are two the epidermis (comprised of the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale) and the dermis. Bad question!Skin Anatomy, Layers of Skin:There are three (3) main layers of skin. From bottom to top the layers are named:HypodermisDermisEpidermisThe epidermis is the outer layer of skin and contains 5 sublayers.
