Answer:sensory nuerone to internuerone to motor neurones
Explanation:
The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.
These receptors send signals as action potential to the spinal cord to the brain.(CNS).
Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.
The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.
The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction
Animal research is critically important for studying variables that can't be ethically tested in human subjects. Ethical regulations ensure the humane treatment of animal subjects and the minimization of pain and distress. Animal research is a privilege granted by society to researchers.
Animal research is critically important for the study of variables that can't be tested ethically in human subjects. Ethical considerations have necessitated strict regulations on animal research, such as the approval of an IACUC and regular inspections of animal facilities. The use of animals in research is a privilege granted by society to researchers, and efforts are made to minimize pain and distress experienced by animal subjects.
