1 List the physiological events that occur between delivery of the stimulus and the start of the recorded response?

The speed of nerve impulse transmission changes as the body ages. In infants, the transmission speed is only about half that seen in adults. By age five, most people have attained the adult velocity. A gradual decline in conduction velocity begins as people reach their 20s, and continues for the remainder of life. Another factor that influences conduction velocity is the length of the nerve itself. An impulse that has to travel a longer distance will take longer. Some nerves are naturally longer than others. Measurement of nerve conduction takes into account the length of the target nerve. Some other factors are: · Initiation of action potential in nerve fibers; · Conduction of impulse; · Release of acetylcholine from the nerve terminals; · Binding of acetylcholine to receptors of the motor end plate; · Depolarization of the end plate; · Initiation of action potential in muscle fibers; · Muscle contraction.


Where do faster neural impulses occur?

Faster neural impulses occur in myelinated neurons, specifically at the nodes of Ranvier where the myelin sheath is interrupted. This allows for a process called saltatory conduction, where the action potential jumps from one node to the next, speeding up the transmission of electrical signals along the neuron.


Can a nerve impulse occur if the excitatory and inhibitory effects are equal?

no


Is conduction occur in fluid?

Yes, conduction can occur in fluids. In fluids, conduction takes place through molecular collisions, where heat is transferred from molecule to molecule. However, conduction is typically less efficient in fluids compared to solids due to the free movement of molecules in fluids.


Does action potentials occur at nodes?

Yes, action potentials occur at the nodes of Ranvier in myelinated neurons. The myelin sheath insulates the axon, forcing the action potential to jump from node to node, a process known as saltatory conduction. This allows for faster conduction of the action potential along the axon.
