Axodendritic synapses result in hypopolarization or hyperpolarization of a neuron, while synapses increase or decrease the release of neurotransmitter into the synapse.

Axoaxonic

Explanation:

The axoaxonic transfer of the electrical signals takes place when the one neurons sends signals from synapse of neuron to the synapse of another neuron.

They mediate the presynaptic inhibition and presynaptic facilitation. This type of transfer of increases or decreases the release of the neurotransmitter into the synapses.

These transfers helps in conduction of the signals from the brain to the various parts of the body in order to generate the response by the body.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
