The key difference between dermatome and cutaneous innervation is that the dermatome is an area of the skin that is innervated by a single spinal nerve. Meanwhile, the cutaneous innervation is an area of the skin innervated by a specific cutaneous nerve. Skin is the largest organ that we have. It is the outermost covering […]
Difference Between Achene and Cypsela
The key difference between achene and cypsela is that the achene is a simple dry indehiscent fruit that originates from a superior ovary. Meanwhile, the cypsela is a simple dry indehiscent fruit which originates from an inferior ovary. Fruits are a unique structure of angiosperms. It is the ripened ovary or mature ovary after fertilization. […]
Difference Between Saltatory and Continuous Conduction
The key difference between saltatory and continuous conduction is that saltatory conduction is the propagation of action potential along myelinated axons while continuous conduction is the propagation of action potential along unmyelinated axons. Saltatory and continuous conduction are two types of transmission of action potentials along the nerves. Saltatory conduction occurs in myelinated axons from […]
Difference Between Viroid and Virusoid
The key difference between viroid and virusoid is that viroid is a small infectious agent composed only of a single-stranded RNA while virusoid is a type of infectious circular single-stranded RNA which requires a helper virus to infect the cell. Viroid and virusoid are two types of infectious particles composed of single-stranded RNA. They are […]
Difference Between Valve and Sphincter
The key difference between valve and sphincter is that valve is a flap-like structure of a hollow organ that allows one-way fluid flow through it while sphincter is a ring-like muscle which is able to contract or close a bodily passage or opening. Valve and sphincter are two structures that carry out similar functions in […]
Difference Between Pollen Tube and Style
The key difference between pollen tube and style is that pollen tube is a hollow tube developed from the pollen after depositing on the stigma while style is a long elongated part of the pistil that provides a path for the pollen tube to reach the ovary for syngamy. A flower has male and female […]
Difference Between Monospermy and Polyspermy
The key difference between monospermy and polyspermy is that the monospermy refers to the normal process of fertilizing an egg cell with one sperm. Meanwhile, the polyspermy refers to the process of fertilizing an egg cell with more than one sperm. Fertilization is the union of an egg cell with a sperm cell. It occurs […]
Difference Between Anatomical and Physiological Dead Space
The key difference between anatomical and physiological dead space is that the anatomical dead space refers to the volume of air that fills the conducting zone of respiration made up by the nose, trachea, and bronchi without penetrating the gas exchange regions of the lung. Meanwhile, the physiological dead space refers to the anatomical dead […]
Difference Between Dwarfism and Cretinism
The key difference between dwarfism and cretinism is that dwarfism refers to a condition of growth retardation that causes an abnormally short adult stature while cretinism is a condition arising from the deficiency of thyroid hormone, which causes dwarfism and mental retardation. Dwarfism and cretinism are two conditions arising due to medical disorder and deficiency […]
Difference Between Interspecific and Intraspecific Hybridization
The key difference between interspecific and intraspecific hybridization is that interspecific hybridization occurs between two related individuals belonging to two different species, while the intraspecific hybridization occurs between genetically divergent two individuals of the same species. Hybridization is the process of mating or crossing off genetically differentiated individuals or groups. The main objective of hybridization is to combine […]
