Anastomosis and end arteries are two terms that are often discussed together in blood circulation. A circulatory anastomosis is a connection between two blood vessels. True end arteries are those arteries that do not have precapillary anastomoses or connections with their neighbouring arteries. The key difference between anastomosis and end arteries is their nature. Anastomosis is a connection […]

The key difference between osteon and osteocyte is that osteon is a cylindrical vascular tunnel formed by an osteoclast-rich tissue while osteocyte is a mature bone cell embedded in the mature bony tissue. Compact bone, also known as cortical bone, is a denser and stronger bone tissue. Compact bone consists of closely packed osteons. The […]

The key difference between somatic and splanchnic mesoderm is that the somatic mesoderm is the outer layer formed after the split of the lateral plate mesoderm. In contrast, the splanchnic mesoderm is the inner layer formed after the split of the lateral plate mesoderm. The process of gastrulation generates the three primary germ layers: ectoderm, endoderm, and mesoderm. Ectoderm gives rise to […]

The key difference between annulus fibrosus and nucleus pulposus is that annulus fibrosus is the outer portion of the intervertebral disc, while the nucleus pulposus is the inner portion of the intervertebral disc. The vertebral column provides protection to the spinal cord. It runs through the central cavity of the spinal cord. Generally, between each vertebra, there […]

The key difference between medulla oblongata and spinal cord is that the medulla oblongata is a part of the brainstem that connects the brain to the spinal cord, while the spinal cord is a long tube-like band of nervous tissue that connects the brain to the lower back. The medulla oblongata and spinal cord are two important parts of […]

The key difference between corpus callosum and corpus luteum is that corpus callosum is present near the cerebral cortex of the brain, while corpus luteum is present in the ovaries. Corpus callosum and corpus luteum are two structures in mammals. However, corpus luteum is also present in reptiles. The main function of the corpus callosum is […]

The key difference between hepatic vein and portal vein is that hepatic vein transports the blood away from the liver into the inferior vena cava while portal vein transports blood from the gastrointestinal tract, gall bladder, pancreas, and spleen into the liver. Blood vessels circulate blood throughout the body. They deliver oxygen to vital organs […]

The key difference between cementocytes and osteocytes is that cementocytes are cells arising from the cementoblast around the root of the teeth, while osteocytes are embedded in a fully formed bony matrix and help in bone remodelling. A tooth consists of enamel, dentin, cementum, and pulp tissue. Cementum is a bone-like structure and a thin […]

The key difference between lamina propria and muscularis propria is that lamina propria is a thin layer of connective tissue that forms a part of the moist linings known as the mucosa, while muscularis propria is a layer of smooth muscle adjacent to the submucosa that lines the gastrointestinal tract in the body. The gastrointestinal […]

The key difference between pronephric mesonephric and metanephric kidney is that pronephric kidney is the earliest nephric stage while mesonephric kidney develops between the sixth and tenth week and metanephric kidney develops and functions between fifth to the twelfth week in the embryonic development stage. The kidneys and urinary tract develop simultaneously from the cloaca […]
