ANSWERS
1: An excitatory postsynaptic potential is received when and excited three presynaptic cells are
connected with the dendrite, axons to raise the action potential. Moreover, the inhibitory
postsynaptic potentials are a temporary factor which is helpful in order to create the
hyperpolarization of postsynaptic membrane which is usually caused by the flow of negative
ions into the postsynaptic cells. Usually, the excitatory postsynaptic cells in living cells are called
chemically when an active presynaptic cell is releases inner currents of neurotransmitter into the
synapse. As for this, some of the binding to the receptors on the postsynaptic cells and create
some of the synapsis that is iron channel typically allows sodium into the self-generating and
excitatory postsynaptic current. Moreover, the electric current is usually is partial and temporal
because they are used to create the negative charge in the cells which can usually in over the
flow of sodium and potassium inside the inner wall that create the inhibition of action potential.
Moreover, this is implying that the sodium ions are enter in the cell then they create a proper
action potential in the body and this is helpful in order to show the peak level as per seen in the
graph which is discussed for the action potential.
2: The central nervous system is usually protecting themselves from the injury which is occur
into the organ or in the body its main line of defence is the bones of the skull and spinal column.
Moreover, the create hard physical barrier for the injury. As per this, of fluid filled is placed
below the bones called as syrinx provide shock absorbance.
In this, the reflex arc consists of major five components which is helpful in order to show
some of the importance as for providing the function the sensory receptors. Its help to provide
the recognition of senses which is occur in the body sensory neurones are usually helpful in order
to flow as a messenger to provide the sensors in the body integration centres are usually collab
the cell in the body together motor neuron is usually connected with each other in order to
provide the responses which is harmful or effective in the context of body. The effect or target
are usually help to bind the receptors and the molecules which is applicable for the positive
approaches in the body.
3: The difference between special sensory, motor and mix carnival nerve in the mix carnival
nerves sensory and motor fibres are usually appeared in the brain surface using the same
structure of root and like spinal nerves only a nerve have sensory ganglia 5, 7, 8, 9 and 10. In
addition to this some carnival nerves carry only senses sensory fibres which is 1, 2 and 8. The
