Where is the hypodermis located?
it is the third layer of skin after your epidermis and dermis then your hypodermis. the hypodermis generally has more areolar and adipose tissue. this is the layer that tattoos are injected into..
Write a note on Dialysis of kidney?
SOME TIME PEOPLE DO NOT NEED to do dialysis because they drink lots of waterhe lung is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into thebloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cellsthat form millions of tiny, exceptionally thin-walled air sacs called alveoli.people are mad because they do this thankyou
What is the gap between cells called?
The nervous system also contains glial (neuroglial) cellsthat occupy the spaces between neurons and modulate their functions The synapse or the synaptic cleft.
How is a cactus adapted to its water?
A cactus is adapted to its water by the specialized functioning of specific body parts. For example, spreading, shallow, fibrous roots seek out the available moisture in the soil. They send any moisture and dissolved nutrients up to the stem for processing and storage. The stem is adapted to keep water and watery products and solutions inside, with little chance of escaping outside the plant. It does so with the help of a flexible, but thickened outer wall and of guard cellsthat control openings that are called stomata, or breathing pores. The effect of both is little chance of escape for any water or watery products and solutions inside.The effect is compounded by the assistance of modified leaves in the form of thorns, spines, spikes, quills, prongs, needles, hairs, or bristles. The leaves channel any moisture available outside - be it dew, fog, or rain - down to the ground, to be taken up by the roots. And so the whole water grabbing, intaking, processing and storing starts all over again.
What is an internal support structure of an animal that gives the body structure and shape?
cytoskeleton is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to, as well as forming organelles that extend from the cell. Indeed, cytoskeletal elements interact extensively and intimately with the cell membrane.[4] Anchoring proteins restricts them to a particular cell surface - for example, the apical surface of epithelial cellsthat line the vertebrate gut - and limits how far they may diffuse within the bilayer. The cytoskeleton is able to form appendage-like organelles, such as cilia, which are microtubule-based extensions covered by the cell membrane, and filopodia, which are actin-based extensions. These extensions are ensheathed in membrane and project from the surface of the cell in order to sense the external environment and/or make contact with the substrate or other cells. The apical surfaces of epithelial cells are dense with actin-based finger-like projections known as microvilli, which increase cell surface area and thereby increase the absorption rate of nutrients. Localized decoupling of the cytoskeleton and cell membrane results in formation of a bleb.Source(s):VV....I...I
Gap between nerve cells?
The gap between nerve cells is called a synapse. Neurotransmitters are released from one nerve cell into the synapse and bind to receptors on the next nerve cell, allowing communication to occur between cells. This process is essential for transferring signals throughout the nervous system.
