The key difference between myelinated and unmyelinated nerve fibres is that the myelinated nerve fibres have myelin sheaths around them while the unmyelinated nerve fibres do not have the sheath. Furthermore, the nerve impulse transmission is faster in myelinated nerve fibers while it is slower in unmyelinated nerve fibers. A nerve cell has three components; […]
Difference Between Nervous Tissue and Nervous System
Key Difference – Nervous Tissue vs Nervous System The ability to respond to stimuli is considered as one of the basic features that can be used to define a living organism. This is achieved through a system where it receives sensory information and integrates them to coordinate a response accordingly. Such a system is […]
Difference Between Preganglionic and Postganglionic Neurons
Key Difference – Preganglionic vs Postganglionic Neurons The nervous system is an important organ system of living organisms.It involves many different functions including coordination of the body functions and responding to stimuli. Neurons are the basic structural and functional units of the nervous system. Different types of neurons are present in the nervous system. […]
Difference Between Absolute and Relative Refractory Period
Key Difference – Absolute vs Relative Refractory Period Action potential of a nerve impulse refers to the phenomenon in which a nerve impulse is transmitted across a neuron. It is a resultant of the difference in concentration of Sodium (Na+) ions and Potassium (K+) ions across the membrane. There are three main phases of […]
Difference Between EPSP and IPSP
Key Difference – EPSP vs IPSP The nervous system is important when responding to different stimuli received by the nerve cells. Both biological and electrochemical components are involved with the signal transmission by the nervous system. Different potentials that build up within the nervous system components cause the transmission of different nerve stimuli. Such […]
Difference Between Resting Potential and Action Potential
Key Difference – Resting Potential vs Action Potential The neuron is considered as the structural unit of the nervous system. It involves the transmission of different nerve stimuli during the cell to cell communication. Neurons send messages electrochemically with the involvement of different ions. In other words, electrically charged chemicals that are the ions […]
Difference Between Ganglion and Synapse
Key Difference – Ganglion vs Synapse Peripheral nervous system is one component of the nervous system of vertebrates. It consists of nerve cells and ganglia. Peripheral nervous system connects central nervous system (brain and spinal cord) to the rest of the body (organs and limbs) for signal transmission and coordination of all body functions. […]
Difference Between Nicotinic and Muscarinic Receptors
Key Difference – Nicotinic vs Muscarinic Receptors Nervous coordination is based on the synaptic transmission of nerve impulses. Different neurotransmitters are involved in nervous transmission. Acetylcholine is one of a neurotransmitter involved in the nervous system. There are two main types of receptors in which acetylcholine acts based on the agonist. The two main […]
Difference Between Neurons and Neurotransmitters
Key Difference – Neurons vs Neurotransmitters The nervous system is the main system which records and distributes information within a person to communicate with the outside body and control the mechanisms within the body. It is composed of a complex network of neurons and glia which transmits messages to and from the brain and […]
Difference Between Parkinson’s and Huntington’s Disease
Key Difference – Parkinson’s vs Huntington’s Disease The key difference between Parkinson’s and Huntington’s disease is that Parkinson disease (PD) is a disorder with rigidity, tremors, slowing of movements, postural instability and gait disturbances usually occurring in old age due to degeneration of the substantia nigra of the midbrain while Huntington’s disease (HD) is a […]
