I think you are talking about the 2 types of virus cycles
the lytic cycle is where a virus invades a bacteria host and quickly inserts its own dna proteins into the bacteria's. the bacteria is then forced to copy the virus dna and reproduce the virus. once all the coppies are made the virus triggers the bacteria to self destruct from the inside, causing the bacteria toburst and releases hundreds of the tiny viruses into the host.
(think of when you get a cold)
the other cycle is the lysogenic cycle these are viruses that enter a host and lay quietly dormant while inserting their own proteins into the dna sequence of the bacteria host. the bacteria unknowingly copies the virus dna along with its own. the host doesn't know the virus has been in them until a stressor such as getting a high temperature of an infection causes the viruses to activate and stop being dormant (like with HIV)<span />
Crossed extensor reflex action prevents one from falling when your foot catches while walking.
Crossed extensor reflex:
- A withdrawal reflex is the crossed extensor reflex. In the withdrawing limb, the extensors relax while the flexors contract, but in the other limb, the opposite happens.
- Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus.
- Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this response.
- They connect with interneurons there, which then stimulate or inhibit alpha motor neurons to the muscles of the opposing leg.
