Which nerve fiber do impulses travel slowly?
Impulses travel more slowly through unmyelinated nerve fiber.
Mechanism of nerve conduction?
Nerve impulses are conducted along the axon in the myelinated nerve fiber with causes the polarity of the nerve.
What is a long nerve fiber that convey electrical impulses to other cells is called a?
A long nerve fiber that conveys electrical impulses to other cells is called an axon.
What is a group of nerve cells called?
A group of nerve cells all together is called a ganglion. These nerve cells are linked by synapses and attach to a nerve fiber.
What is the function of stratum basale?
This is the deepest layer of the skin structure and, as such, acts as stem cells since they are the least differentiated or least specific type of skin cell. As they migrate upward, environmental factors and neighboring cells increasingly cause them to become more specific cell types. Ocassionally called the "basement membrane," found to be essential for proper healing after thermal injuries to the skin. Was eventually found to be the reason why earlier attempts at skin grafts using only upper skin cells were found not to be effective in 3-rd degree full thickness burns. Modern skin grafts now use a layer of these stratum g. cells on the artificial skin, followed by other cells added later. The result has been a marked improvement in the rate of successful skin grafts.
A unique touch receptor formed from a stratum basale cell and a nerve fiber is a?
merkel cell
Unique touch receptor formed from stratum basal cell?
A unique touch receptor formed from stratum basale cell (and a nerve fiber) is a merkel cell.
What is a unique touch receptor formed from a stratum basale cell and a nerve fiber?
The skin, all 6-10 lb. (~3-4 kg) and 20 square feet in an adult, is a giant, washable, stretchable, tough, water-proof sensory apparatus covering your whole body. One of the endings that detect things is a encapsulated nerve ending formed by the tiny nerve cell of a dorsal root ganglion cell in next to a Merkel cell found in the basal layer hairy skin, in hair follicles, and in oral and anal mucosa.This called the Merkel disc and is a sensory receptor for pressure and texture information.
What epithelial tissues forms the epidermis of the skin?
Epithelial tissue? Maybe. I Think... Also Muscle Cell Forms A Muscle Tissue And A Nerve Cell ( Neuron in Posh Standards ) forms a nerve tissue
What are the names of the 2 ions necessary to create an electric current in a nerve fiber?
potassium
What is required to maintain nerve fiber sheath?
required to maintain nerve fiber sheath
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
Which nerve fiber do impulses travel slowly?
Impulses travel more slowly through unmyelinated nerve fiber.
What fiber transmits impulses to the central nervous system?
The nerve fiber.
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.

Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
What is non-myelinated nerve fiber?
a nerve fiber that lacks the fatty myelin insulating sheath. Such fibers form the gray matter of the nervous system, as distinguished from the white matter of myelinated fibers. Also called nonmedullated nerve fiber.
