What else can I help you with?
The head and the torso lack what epidermal layer?
The head and torso lack the stratum lucidum epidermal layer found in areas with thick skin, such as the palms and soles. Instead, the head and torso have thinner skin with fewer epidermal layers.
What stratum is absent from most epidermis?
The stratum lucidum is absent from most epidermis, except for in areas with thick skin, such as the palms of the hands and soles of the feet. The stratum lucidum is a clear layer of dead skin cells found between the stratum granulosum and stratum corneum.
What do finger prints come from?
Fingerprints come from the lowest layer, or stratum of the epidermis: the stratum basale. In the palms of hands and the soles of feet dermal papillae form (small pockets of dermis pressing into the epidermis) causing increased surface area of the stratum basale and increased skin cell division, when the extra skin cells are pushed upward, ridges form along the surface of the skin and fingerprints are made.
What are fingerprints a result of?
Fingerprints are a result of the ridges and patterns on the skin of our fingers, palms, and soles. These unique patterns are formed during fetal development and remain constant throughout a person's life.
Do you have pores on your palms?
Yes, there are pores on the palms of your hands.
The head and the torso lack what epidermal layer?
The head and torso lack the stratum lucidum epidermal layer found in areas with thick skin, such as the palms and soles. Instead, the head and torso have thinner skin with fewer epidermal layers.
What stratum is present in thick skin but not in thin skin?
Stratum lucidum (in thick skin) is a well defined epidermal layer found under the corneum region of the skin of the palms and soles. Main function of this stratum is to help the skin handle friction and also waterproof it. It is a thin transitional layer of epidermis found between the 'horny' and 'granular' layers.
What is the stratum lucidum?
This is one of layer in epidermis of the skin. Lucidum means transparent. You do not have typical nuclei to be seen in this layer. They have got disintegrated for lack of blood supply, probably.
What layer is present only in thick skin?
The stratum lucidum, which is present in the thick skin of the palms and soles, is absent in thin skin
Which layer of the epidermis is found in only a few areas of the body?
The stratum lucidum layer of the epidermis is found in only a few areas of the body, such as the palms of the hands and the soles of the feet. It is a thin, clear layer that is located just above the stratum granulosum.
Which layer is the epidermis?
The epidermis has either 4 or 5 layers depending on the location of your body. Stratum Corneum Stratum Lucidum (only on the soles of your feet and palms of your hands) Stratum Granulosum Stratum Spinosum Stratum Basale
What stratum in the skin covers the palms and fingertips?
stratum lucidum.
What cells make up the epidermis?
The epidermis is composed of 4-5 layers depending on the region of skin being considered. Those layers in descending order are the cornified layer (stratum corneum), clear/translucent layer found only on the palms and soles (stratum lucidum), granular layer (stratum granulosum), spinous layer (stratum spinosum), and basal/germinal layer (stratum basale/germinativum). The term Malpighian layer (stratum malpighi) is usually defined as both the basal and spinosum layers as a unitThe Layers of the Epidermis are.1- Stratum Corneum ( Most Superficial )2- Stratum Granulosum3- Stratus Spinosum4- Stratum Basale or Basal Layer ( Deepest Layer )* Stratum Corneum = keratinized,dead,flattened scale-like and non-nucleated cells which are continuously shed as flake-like residue. * Stratum Lucidum = thin,clean layers found only in epidermis of the lips,palms and soles. * Stratum Granulosum = one or more layers of granular cells that contain fiber ang keratin and shriveled nuclei. * Stratum Spinosum =spiny layer, several stratified layer of cells in contact with centrally located, large oral nuclei and spine like process. * Stratum Germinativum = basal layer, simple layer of cuboidal cells in contact with the epidermis.From deepest to superficial: Stratum germinativum (also called "stratum basale"), stratum spinosum, stratum granulosum, stratum lucidum (palms & soles), and stratum corneum, the outermost layer that is composed of dead skin cells.
What is the layer of skin called that covers the soles of your feet?
The stratum lucidum is a layer of skin found on the palms and soles. It isn't found on other parts of the body.
What is the clear layer of the epidermis consisting of small transparent cells?
The stratum lucidum is the clear layer of the skin. It is found only in the thick skin of the palms and soles.
Which is the most complex layer of the skin?
The epidermis is a layer of skin. The epidermis has 5 layers (additional layer is stratum lucidum) on the palms of the hands and the soles of the foot. On other parts of the skin, the epidermis has 4 layers. The thickest layer of the epidermis is stratum spinosum (the second bottom layer).
What stratum is absent from most epidermis?
The stratum lucidum is absent from most epidermis, except for in areas with thick skin, such as the palms of the hands and soles of the feet. The stratum lucidum is a clear layer of dead skin cells found between the stratum granulosum and stratum corneum.
