Answer:
The flow of information within a neuron is intracellular signalling whereas the flow of information between neuron is inter cellular signalling.
Explanation:
- Central nervous system consist of 2 types of cell that are neurons and glia where neurons are the information processing structure in Central nervous system.
- A typical neuron consists of 4 parts called- cell body,processes,dendrite and axons.
- Cell body is the metabolic controlling center and from cell body, processes structure is extended which conduct signal flow to or away from the cell body.
- Dendrites receive the incoming signals and the outgoing signals to the other neurons are flow along with the help of axons.
- Neurons have an unique features of intracellular and inter cellular signalling.
- Intracellular signalling is proceed within the cells and inter cellular signalling is is transmitted between the cells.
- The communication that is generated between the neurons are achieved by synapses.This process is called as neurotransmitter.
Answer:
the immune system needs B cells and memory B cells form into memory cells so that remember the same pathogen and the antibody used to take it down for faster antibody production in future infections when most of the same antigens infect the body again.
Explanation:
When the body senses foreign substances like antigens, the immune system works to recognize the antigens and get rid of them. B Cells that have a certain antibody codes/proteins for the specific antigen are triggered or activated by T cells to make the specific antibodies, or immunoglobulins, to use against the antigens, by locking onto the antigen and putting the antibodies into the antigen directly.
Answer:
Fungiform
Explanation:
The papillae located mainly on the tip and sides of the tongue that contain only a few taste buds each are the Fungiform papillae.
The fungiform papillae are broad flat structures that house taste buds in the central portion of the dorsum (back) of the tongue. These papillae were thought to resemble a fungus: a little mushroom. The literal meaning of Fungiform is mushroom-shaped.
