What is the Immune System? The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens like bacteria, viruses, fungi, and parasites. Its primary function is to recognize and neutralize these foreign invaders to maintain the body’s health. This System is made up of…
Introduction The brachial artery is a major blood vessel of the upper arm, extending from the shoulder to the elbow. It is the main artery supplying blood to the arm and plays a crucial role in maintaining adequate blood flow to the tissues of the upper limb. It is the continuation of the axillary artery…
Introduction of the tibia bone Embryology and Development of the Tibia Bone Embryology and Development of the Tibia Bone is as mentioned below , Region of the tibia bone The Region of the tibial bone is described below, The Proximal end of the tibia bone The Proximal end of the tibia bone is as follows…
Introduction introduction of the femur bone is as described follows , The longest and strongest bone in the human body is the femur, also referred to as the thigh bone. It plays a crucial role in providing structural support and bearing the majority of the body’s weight during activities such as standing, walking, and running….
What is Striated Muscle Tissue? Sarcomeres, which are recurring functional units seen in muscle tissue, are characteristics of striated muscle tissue. The striated appearance seen in microscopic photographs of this tissue is caused by the presence of sarcomeres, which appear as a series of bands seen along the muscular fibers. Two varieties of striated muscle…
What is Skeletal Muscle? Commonly referred to as muscles, skeletal muscles are organs of the vertebrate muscular system, usually linked to a skeleton’s bones via tendons. Skeletal muscle cells, sometimes referred to as muscle fibers, are considerably longer than those of other forms of muscular tissue. Because of how the sarcomeres are arranged, the muscular tissue…
Introduction of the humerus bone The humerus is a long bone located in the upper arm or forelimb of vertebrates, extending from the shoulder to the elbow. Defines the human brachium, or arm. It articulates distally at the elbow joint with the radius and ulna, and proximally with the glenoid through the glenohumeral (GH) joint….
What Is Muscle Hypertrophy? Muscle hypertrophy refers to the process of increasing the size of skeletal muscle fibers through the enlargement of individual cells. The process of developing larger skeletal muscles through an increase in the size of their constituent cells is known as muscle hypertrophy or muscle development. Sarcoplasmic hypertrophy, which emphasizes greater muscle…
What is a Muscle Contraction? The activation of tension-generating areas inside muscle cells causes contractions in the muscles. In physiology, a muscular contraction does not always imply a shortening of the muscle since stress can be created in the muscle without a change in length, as in the case of keeping a heavy object in…
What is a Muscle Tone? Due to reciprocal and hierarchical anatomical relationships, muscle tone is a dynamic and complicated condition. Its input and output systems control it and interact crucially with the demands of task performance and power. In simple terms, tone is a motor control concept that maintains power balance inherently. The brainstem reticular…
