Ceruminous glands secrete?

The quadriceps femoris group is a group of four muscles located in the anterior compartment of the thigh. These muscles are responsible for extending the leg at the knee joint. The four muscles that make up the quadriceps femoris group are the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis.

The vastus lateralis is the largest of the four muscles and is located on the lateral side of the thigh. It originates from the greater trochanter of the femur, the lateral lip of the linea aspera, and the lateral intermuscular septum. It inserts into the patella and the tibial tuberosity via the patellar tendon. The vastus lateralis is responsible for extending the leg at the knee joint and is also involved in stabilizing the patella.

Ceruminous glands are specialized sweat glands located in the skin of the ear canal. These glands secrete a waxy substance called cerumen or ear wax. Ear wax helps to lubricate and protect the skin of the ear canal and prevent the entry of foreign particles, such as dust and insects, into the ear. It also has antibacterial properties that help to protect the ear from infection. The amount and composition of ear wax vary from person to person and can be affected by factors such as age, genetics, and environmental conditions.
