The key difference between cervical thoracic and lumbar vertebrae is their location. Cervical vertebrae are in the neck region while thoracic vertebrae are in the thorax (chest region) and lumbar vertebrae are in the lower back region. There are 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae. The vertebral column is a part […]
Difference Between Spinal Cord and Vertebral Column
The spinal cord is a major part of the central nervous system which comprises tubular nerve bundle while the vertebral column is a bony, segmented structure which supports head and thorax. The spinal cord runs inside the vertebral column, and vertebral column protects the spinal cord. This is the key difference between spinal cord and […]
Difference Between Atlas and Axis Vertebrae
The key difference between atlas and axis vertebrae is that the atlas vertebra is the topmost vertebra which holds the skull while axis vertebra is the second topmost vertebra which provides an axis to rotate the skull and atlas vertebra when the head moves side to side. Cervical vertebrae are the vertebrae in the neck […]
Difference Between Peristalsis and Segmentation
Key Difference – Peristalsis vs Segmentation Peristalsis and segmentation are two types of the smooth muscle movements of the GI tract. Peristalsis pushes the food downward in one direction while segmentation does not cause for net movement of food inside the GI tract. This is the key difference between peristalsis and segmentation. Digestion and […]
Difference Between Mitral Valve and Tricuspid Valve
Key Difference – Mitral Valve vs Tricuspid Valve Heart valves are very important as they allow a unidirectional flow of blood to and from the heart. This ensures that the blood circulation takes place in an efficient manner. There are four main valves that are involved in blood circulation in mammals. They are the […]
Difference Between First and Second Premolar
Key Difference – First vs Second Premolar Premolars are the teeth that are situated in between the canine and the molar. They are also known as the transitional teeth and mainly involved in the mastication of food. There are two types of premolars; the mandibular premolar and maxillary premolar. In humans, the premolars are […]
Difference Between Skeletal and Smooth Muscle Contraction
Key Difference – Skeletal vs Smooth Muscle Contraction Muscles provide a shape to the body and involve in the movement and various other functions of the body. They involve in different activities of the body that are controlled by both voluntary and involuntary controls. There are three main types of muscles namely skeletal muscle, […]
Difference Between Notochord and Nerve Cord
Key Difference – Notochord vs Nerve Cord Chordates are more developed and advanced organisms with sophisticated cellular structures and metabolic pathways. They possess characteristic features that distinguish them from other organisms. These characteristic features mainly include the presence of a notochord and a nerve cord. The notochord and nerve chord involve providing distinct functions. […]
Difference Between Actin and Myosin
The key difference between actin and myosin is that actin exists as thin, short filaments while myosin exists as thick, long filaments in myofibrils of the muscle fibers. Actin-myosin contractile system is the main contractile system of all muscular tissues, and it works based on the interactions between the two proteins – the actin and […]
Difference Between Origin and Insertion
The key difference between origin and insertion is that origin is the bone attachment at the stationary end of the muscle while insertion is the bone attachment to the mobile end of the muscle. A muscular tissue mainly comprises of all the contractile tissues of the body including skeletal, cardiac, and smooth muscles. Muscles are […]
