Semimembranosus, semitendinosus, and biceps femoris ... The hamstrings
Yes, the hamstring muscles cross the hip joint. They originate from the ischial tuberosity of the pelvis and extend down to the knee joint, playing a crucial role in both hip extension and knee flexion. This dual functionality makes them important for various movements, such as running and jumping.
The hamstrings attach to the ischial tuberosity of the pelvis and extend down to the tibia and fibula bones in the lower leg.
The gluteal muscles The gluteus maximus is the uppermost of the three muscles. It is the largest of the gluteal muscles and one of the strongest muscles in the human body (see Muscle). It inserts at the iliotibial band and the gluteal tuberosity of the femur. Its action is to extend and outwardly rotate hip, and extend the trunk. Powerlifting exercises which are known to significantly strengthen the gluteus maximus include the squat and the deadlift. The leg press also uses the gluteus maximus.
The quadriceps are a group of muscles on the front of your thighs., There are four distinct muscles that make up the quadriceps muscles.These muscles are called the vastus intermedius, the vastus medialis, the vastus lateralis, and the rectus femoris. The quadriceps are also known simply as the quads.The group inserts on the tibial tuberosity (a knot below the patella).Since the quadriceps extend over the kneecap (patella), they also help to keep your kneecap in its proper position in a groove in the end of your thigh bone.
A very powerful muscle called as quadriceps femoris is attached to the tibial tuberosity. Vast-us medialis, vast-us intermedius and vast-us lateral-is come from femur bone. Whereas rectus femoris comes from hip bone.
Extensor muscles extend or straighten a body part.
The insertion of all quadriceps muscles is the patella (kneecap), which is then connected to the tibia through the patellar tendon. The quadriceps muscles include the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius, all of which work together to extend the knee joint.
The brachial plexus are nerves that leave the cervical vertebrae (but originate in the brain) and extend to peripheral structures (muscles/organs) to transmit motor and sensory nerve impulses.
