hamstring group

Examples of hamstring group in the following topics:

• Muscles that Cause Movement at the Knee Joint

  • Three sets of muscles (popliteus, quadriceps and hamstrings) allow for movement, balance, and stability at the knee joint.
  • These muscles are sometimes termed the hamstring group.

• Pulled Hamstring and Charley Horse

  • A strained hamstring, also known as a pulled hamstring, is defined as an excessive stretch or tear of muscle fibers and related tissue.
  • Straining of the hamstring , also known as a pulled hamstring, muscle pull, or Charley Horse is defined as an excessive stretch or tear of muscle fibers and associated tissues.
  • Grade 3 - Bruising due to strained hamstring, horizontal lines show where bandage was.
  • A grade three hamstring strain is a severe injury.
  • Lower grade strains can easily become worse if the hamstring is not rested properly.

• Pulled Groin

  • The pectineus muscle is innervated by the femoral nerve, and the hamstring portion of adductor magnus is innervated by tibial nerve.
  • This difference in innervation has caused some dispute whether or not the pectineus belongs to this groin and adduction group even though it still adducts the thigh.

• Running Injuries

  • They include "runner's knee" (pain in the knee), shin splints, pulled muscles (especially the hamstring), twisted ankles, iliotibial band syndrome, plantar fasciitis, Achilles tendonitis , and stress fractures.
  • Engaging the hips, driving the thigh or knee, pushing off with the ankles and not the hamstrings, pawing your legs back, and erect posture are some of the key actions in proper running technique.
  • Running injuries can be from a lack of strength, stride length, and pushing off with the hamstrings and not the ankle.
  • The hamstrings and gluteus maximus are not involved in the push off phase of running, contrary to popular belief.

• Back Injuries and Heavy Lifting

  • Sedentary lifestyles most often lead to weak abdominal muscles and hamstrings.

• Sprain and Strain

  • Pulled hamstring after four days.

• Blood Groups and Blood Types

  • Therefore, a group A individual can only receive blood from individuals of groups A or O types, and can donate blood to individuals of groups A or AB.
  • Therefore, a group B individual can only receive blood from individuals of groups B or O, and can donate blood to individuals of groups B or AB.
  • Therefore, an individual with type AB blood can receive blood from any group, but can only donate blood to another group AB individual.
  • Therefore, a group O individual can only receive blood from a group O individual, but they can donate blood to individuals of any ABO blood group (i.e.
  • Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cell.

• Muscles that Cause Movement at the Hip Joint

  • Hip joint muscles are divided into four groups according to their orientation and function.
  • All of the lateral rotator group muscles originate from the pelvis and attach to the femur.
  • Piriformis - The piriformis is the most superior of the lateral rotator group muscles.
  • The iliacus and psoas major comprise the iliopsoas group.
  • The iliacus and psoas major comprise the iliopsoas group.

• Arrangement of Fascicles

  • Skeletal muscles are grouped into fascicles, which are bunches of muscle fibers surrounded by a perimysium.
  • Key muscle groups and the associated vascular and nervous systems can also be separated from other tissue, such as in the upper arm.
  • These groupings are called fascial compartments.
  • The fascia surrounding a muscle or muscle group does not contain many blood vessels, but is rich with sensory receptors.
  • Within this is a layer termed the epimysium which splits inwards into the muscle as the perimysium dividing muscle fibers into groups termed fascicle.

• Classification of Nerves

  • Fibers of the A group have a large diameter, high conduction velocity, and are myelinated.
  • Fibers of the B group are myelinated with a small diameter and have a low conduction velocity.
  • Fibers of the C group are unmyelinated, have a small diameter, and low conduction velocity.
  • The lack of myelination in the C group is the primary cause of their slow conduction velocity.
  • C fiber axons are grouped together into what is known as Remak bundles.
