Introduction The cervical spine is comprised of the initial 7 vertebrae, alluded to as C1-7 (see the pictures underneath). It has the capability to give versatility and soundness to the head while interfacing it with the moderately stationary thoracic spine. The cervical spine might be separated into 2 sections: upper and lower. The cervical spine,…
Arteries and veins are fundamental components of the circulatory system, playing distinct yet complementary roles in the transportation of blood throughout the body. While both are blood vessels, they exhibit notable differences in structure, function, and the composition of blood they carry. Introduction: The blood vessels in your body cover more than 60,000 km. There…
Introduction Three different types of blood vessels make up our circulatory system: capillaries, veins, and arteries. Unlike veins, which bring blood to the heart, arteries move blood away from the heart. The walls of arteries are more elastic and thicker than those of veins because they carry the blood that the heart pumps out. This…
Introduction In the distal part of the adductor magnus muscle, the popliteal artery is a deeply situated continuation of the femoral artery opening. It passes through the popliteal fossa before dividing into the anterior and posterior tibial arteries at the popliteus muscle’s bottom border. The popliteal artery, which crosses the intercondylar fossa, is the deepest…
Nerve tissue is a fundamental component of the nervous system, responsible for transmitting signals throughout the body. Comprising of specialized cells called neurons, nerve tissue is characterized by its unique structure and function. What is a Nerve Tissue Composition? Within the neurological system, neurons are cells that send messages to other neurons, muscles, or gland…
The brachial artery is a major blood vessel situated in the upper arm. It is one of the main arteries responsible for supplying oxygenated blood to the arm and forearm regions. Arising from the axillary artery at the lower border of the teres major muscle, the brachial artery descends along the medial aspect of the…
Introduction The superior mesenteric artery (SMA) is a major blood vessel in the human body, arising from the abdominal aorta just below the celiac artery at the level of the first lumbar vertebra It begins at the level of the L1 vertebrae on the anterior surface of the aorta, about 1 centimetre below the celiac…
Introduction The thick, robust tendon that joins the quadriceps muscles to the patella (kneecap) is called the quadriceps tendon. It is an essential component of the leg’s extensor mechanism and is critical in knee joint movement. The four quadriceps muscles, which are found in the front of the thigh, converge to produce the quadriceps tendon….
What is a Skeletal Muscle? Skeletal muscles (often referred to as muscles) are the organs of the vertebrate muscular system and are usually connected to the bones of the skeleton by tendons. Muscle cells in skeletal muscle are much longer than in other types of muscle tissue and are often called muscle fibers. Skeletal muscle…
Overview The term “dermatome” is a combination of two Greek words: “derma” meaning “skin” & “tome” meaning “cutting” or “thin segment”. Dermatomes are areas of the skin whose sensory distribution is innervated by afferent nerve fibers from the dorsal root of a single spinal nerve root, which is the portion of a peripheral nerve that…
