What is the Fick Principle? The Fick principle and Fick equation are named after A. Fick, a cardiovascular physiologist who developed the principle in the 1870s. The amount of oxygen delivered to tissue can be calculated using the Fick principle. The Fick principle states that the amount of a substance removed from the blood passing through an organ per unit of time can be calculated by multiplying the blood flow through the organ times the arterial concentration minus the venous concentration of that substance.  The Fick principle can be used to calculate oxygen consumption for the entire body or for a specific tissue or organ. In the case of oxygen consumption for the entire body, the Fick principle results in the following equation:  VO₂ = Q × a-v O₂ difference  where  Q equals cardiac output and, a-v O₂ difference  equals arterial-mixed venous oxygen difference . This equation can be used to calculate...

Abdominal crunches primarily work on abdominal muscles and it is widely used as general body workout and abdominal muscles strengthening. How to Do Abdominal Crunches? 1. Lie down on the floor on your back and bend your knees, placing your hands behind your head or across your chest. Some people find that crossing the arms over the chest helps them avoid pulling on the neck. 2. If you are putting your hands behind your head, your fingers should gently cradle your head. The idea is to support your neck without taking away from the work of your abs. 3. Pull your belly button towards your spine in preparation for the movement.  4. Slowly contract your abdominals, bringing your shoulder blades about one or two inches off the floor. 5. Exhale as you come up and keep your neck straight, chin up. Imagine you're holding a tennis ball under your chin. That's about the angle you want to keep the chin the entire time. 6. Slowly lower back down. 7. Repetatio...

The Pectoralis major is a muscle of the pectoral region. This muscle along with the Pectoralis minor, Subclavius and Serratus anterior forms the pectoral region. It is the largest muscle in this region. Morphologically it is thin and fan-shaped. It is characterized by 2 heads, the large Sternocostal head, and the small Clavicular head. ORIGIN The Sternocostal head arises from- Medial parts of 2nd-6th costal cartilages and aponeurosis of the external oblique muscle of the abdomen. Lateral half of the anterior surface of the sternum up to 6th costal cartilage. The Clavicular head arises from the medial half of the anterior aspect of the clavicle. INSERTION Pectoralis major is inserted by a bilaminar tendon on the lateral lip of the bicipital groove of the humerus. This tendon has an anterior lamina and a posterior lamina. Anterior lamina is thick, short and is formed by clavicular fibers. Posterior lamina is thin, long and is formed by sternocostal and aponeurotic fi...

According to WHO( World Health Organisation), Osteoporosis is a systemic skeletal disease characterized by low bone mass & microarchitectural deterioration of bone tissue leading to enhanced bone fragility & a consequent increase in fracture risk.   Osteoporosis is far commonest Metabolic Bone Diseases. It occurs when the Rate of Bone Resorption exceeds Rate of Bone Formation. This weakness in bone and brittleness results in the reduction of BMD due to a deficiency of Vitamin D and Calcium. Deficient calcium absorption from the intestine. ↓ Stimulates parathyroid gland ↓ Parathyroid Hormone resorbs Calcium from bone ↓ OSTEOPOROSIS Classification: Primary Osteoporosis : Type 1 - Postosteoporosis Type 2 - Senile osteoporosis Secondary Osteoporosis  Due to some diseases such as Endocrine, Malignancy, prolong intake of medicine eg: steroids, antiepileptics, etc. Causes for osteoporosis: Senility Post immobil...

The adductor muscles refer to five muscles which are pectineus , gracilis, adductor longus, adductor brevis, and adductor Magnus.  pectineus is flat muscle, which is quadrangular in shape and positioned anteriorly in the thigh. it is also sometimes referred to as a most anterior adductor of the hip. Origin of Pectineus Pectineus originates from a pectineal line of the pubis. Insertion Origin of Pectineus Pectineus is inserted on inferior from lesser trochanter to linea aspera. Action Origin of Pectineus Pectineus is responsible for adduction, flexion & medial rotation thigh . Nerve Supply Pectineus is supplied by Femoral & obturator nerve combined. Arterial Supply Pectineus muscle is blood supplied by Medial circumflex femoral branch of the femoral artery and obturator artery.

Biceps brachii Commonly known as the biceps is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. It is a large muscle. The biceps brachii muscle is one of the chief and prominent muscles of the arm. Origin:  Biceps brachii has two head. Short head originates from the tip of coracoid process of scapula; Long head originates from supraglenoid tubercle of scapula. Insertion: It is Inserted at Tuberosity of radius and fascia of forearm via bicipital aponeurosis . Action:  Supinates forearm and, when it is supine, flexes the forearm Nerve Supply:  Biceps brachii supplied by Musculocutaneous nerve (C5 and C6 ). Arterial Supply: Muscular branches of the brachial artery.

Movement in the spine and hip joint make it possible for the pelvis to be established in the variety of Positions. it may be inclined or tilted in anteroposterior directions, laterally or rotated. which is known as Pelvic Tilt. Types of Pelvic tilt anteroposterior Tilt lateral tilting Rotation of Pelvis 1) Antero-posterior Tilt:  pelvic tilt measurement is performed in three ways in the erect position. It is possible to measure the angle at which the imaginary line is drawn through the pubic symphysis and the lumbosacral angle in relation to the horizontal line. The pelvic tilt is said to be normal when the angle of the os pelvic tilt is between 50 ° and 60 ° when the anterior upper iliac spines and the symphysis pubis are in the same vertical plane.  The angle is measured by a pelvic inclinometer . One arm of the inclinometer on the symphysis and the other on the PSIS. The normal range is 30 °. The increased angle of pelvic tilt may be referred to as f...
