Tubectomy is the sterilization process in the female that prevents the passage of eggs from reaching the uterus for implantation, and it is a small incision technique. Vasectomy is the sterilization process of the male that prevents the passage of sperms, and it is also the small incision technique. These two methods are known as permanent methods of sterilization or contraception. These methods are advised to any one of the partners either male or female as a way to prevent any more … [Read more...]
Difference Between Afferent and Efferent Neurons
The afferent or sensory nerve transfers the messages or signals from various organs to the spinal cord or brain. In contrast, efferent nerve or motor nerve transfer the messages or signals from the spinal cord or brain to multiple organs. That means their role is opposite, but they work in transferring signals between organs and spinal cord or brain. When you rub your palms, do exercises, hit a ball, there is the involvement of afferent and efferent neurons that are responding to the … [Read more...]
Difference Between Homologous and Analogous Structures
Homologous structures are such structures that do not show exact similarity in their appearance and function but are linked with their common ancestor. On the other hand, analogous structures are such structures that are similar in their function and appearance but do not have any links between their ancestors. The arms of humans, legs of dogs, are the common examples of homologous structure, where they must have diverged and evolved as different beings. The wing of insects, birds, bats and … [Read more...]
Difference Between Menarche and Menopause
The onset of the first menstrual period in the female adolescent is the menarche, while the termination or end of the menstrual cycle in the females is known as menopause. These are the two significant physical and biological milestone in the female's life. The studies on these events reveal that partially genetic and partially non-genetic factors (environmental factors, lifestyle, etc.) influence the age at which menarche and menopause in females. Although there are various medical issues … [Read more...]
Difference Between Dendrite and Axon
Dendrite refers to the 'Trees' in Greek, so these are the branched small extension of the nerve cell. Axon refers to the 'axis' in Greek, so axon is the long slender like protrusion of the neuron or nerve cell. Secondly, dendrite receives messages or information or electrochemical impulses from the external environment or other neurons, so they work as the input for the neuron. The role of the axon is to send messages or any information or electrochemical impulses to the external environment … [Read more...]
Differences Between Actin and Myosin
Actin is the collective molecules of protein from which thin bands are formed. On the other hand, Myosin is the group of protein by which thick bands are formed. Actin and Myosin are responsible for various types of cellular movements, and the most striking one is the muscle contraction, that provides the best-model to understand the role of actin and myosin. Now, to know the function of actin-myosin, it is necessary to gather bit information about muscles contraction. The cellular and … [Read more...]
Difference Between Autosomes and Sex Chromosomes
The chromosomes, apart from the sex chromosomes, are known as autosomes of an organism. The number of chromosomes varies from one organism to others. In humans, there is a total of 46 chromosomes or in pair of 23. Out of these, 2 are sex chromosome (XX or XY), and 44 are autosomes. Mice have in all 40 chromosomes, out of which 38 are autosomes, and 2 are sex chromosomes. Abnormalities in the chromosomes (autosomes or sex chromosomes) results in the retardation in growth of an organism or … [Read more...]
Difference Between Anatomy and Physiology
The word 'anatomy' means 'structure', while 'physiology' refers to 'function'. We can elaborate by saying that anatomy is the detailed study of different body parts, their organization, and their interrelationship, but how these body parts and organs play their specific role in a coordinated manner is termed as physiology. An understanding of these terms is not only beneficial to health professionals and their career; instead, it helps us know about your own body and its wellness. Familiarity … [Read more...]
Difference Between Rods and Cones
Rods and Cones are the photoreceptors, useful in providing vision to the eyes. Rods provide vision during dim light or night also known as scotopic vision, whereas cones provide vision during day time or at bright light also known as photopic vision. Secondly, rods do not support the colour vision, but cones are capable of colour vision, with high spatial acuity — the level of the light where both the types of work, is called a mesopic vision. Eyes are one of the primary sense organs found … [Read more...]
Difference Between Oestrogen (Estrogen) and Progesterone
Oestrogen or estrogen is the female steroid hormone known for the development of the female reproductive system, while progesterone is also another type of female steroid hormone known for releasing corpus luteum and supports the pregnancy. These are the types of steroids hormones and are categorized under two category which are corticosteroids and sex steroids. Among which the mineralocorticoids and glucocorticoids are the are the types corticosteroids, while oestrogen or estrogen, … [Read more...]
