Hypertrophy vs Hyperplasia Hyperplasia and hypertrophy are two terms used in pathology to explain growth abnormalities in living tissues. Usually under normal physiological stimulation, tissue display normal orderly growth patterns. Under excessive or abnormal stimulations, the tissues grow out of the ordinary. Being two different pathological entities, there are many differences between hyperplasia and hypertrophy, […]
Difference Between Upper and Lower Motor Neuron
Upper vs Lower Motor Neuron The conduction of motor and sensory nerve impulses to and from the brain is basically carried out by sensory (ascending) and motor (descending) tracts, and pathways in the spinal cord. The names of the pathways are given according to their position in the white matter, and their beginning and […]
Difference Between Gonads and Gametes
Gonads vs Gametes Gonads and gametes are two most important components of the reproductive system in organisms. These components are involved in sexual reproduction, which occurs via the fusion of two gametes from two different parents and has the end result of genetically unequal offspring. Sexual reproduction, basically, requires the production of gametes in […]
Difference Between Uvula and Epiglottis
Uvula vs Epiglottis Uvula and epiglottis are important parts, which contribute to carry out functions in both respiratory and digestive system, in mammals. Unlike in the other animals, the adult humans have a space between uvula and epiglottis. However, the newborn human has an interlocking uvula and epiglottis, where they touch each other like […]
Difference Between Primary and Secondary Lymphoid Organs
Primary vs Secondary Lymphoid Organs The human immune system is an important system, which facilitates major defensive actions against the foreign particles and microorganisms. The tissue aggregates where leukocytes mature, differentiate, and proliferate are called the lymphoid organs. They are mainly composed of epithelial cells and stromal cells, arranged either into organs or accumulation […]
Difference Between Male and Female Skull
The key difference between male and female skull is that male skull is heavier due to the presence of thicker bones while female skull is lighter due to the presence of thinner bones. The human skull is an important part of the skeletal system, which basically provides sites for facial muscle attachments and forms a cranial […]
Difference Between Superior and Inferior Vena Cava
The key difference between superior and inferior vena cava is that superior vena cava brings deoxygenated blood into the right atrium of the heart from the upper half of the body while inferior vena brings deoxygenated blood into the right atrium of the heart from the lower part of the body. Superior vena cava and […]
Difference Between Bronchi and Bronchioles
Bronchi vs Bronchioles The human respiratory system is basically made up two lungs, located inside the upper part of the body cavity. Lungs increase the gas exchange surface area while minimizing the evaporation. However, the gas exchange takes place deep in the lungs, in alveoli, which are found at the end of a long […]
Difference Between Sensory and Motor Nerves
Sensory vs Motor Nerves The nervous system controls all activities of the body, both voluntary and involuntary. The somatic nervous system regulates all the voluntary controlled activities such as walking, talking etc. while the autonomic nervous system controls the activities under involuntary control, such as digestion, dilation etc. (Read more: Difference Between Somatic and […]
Difference Between Atria and Ventricles
The key difference between atria and ventricles is their function. Atria receive blood from body parts and lungs and pass the blood to ventricles, which then pump the blood received from atria to the body parts, including the lungs. The human circulatory system has a four-chambered heart with two separate atria and two separate ventricles. The main […]
