Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
For a limb to move, you need muscles, nerves, and a signal from the brain. The brain sends signals through nerves to the muscles, which contract and allow the limb to move.
The median nerve controls muscles in the forearm and hand, providing sensation to the palm and fingers. The iliohypogastric nerve supplies motor function to the lower abdominal muscles and sensory innervation to the skin over the lower abdomen and groin area.
The lower limb attaches at the hip region, where the femur (thigh bone) articulates with the pelvic bone to form the hip joint.
The flexor carpi ulnaris muscle is an upper limb muscle that has double innervation from both the ulnar and medial nerves.
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.

Medial aspect of the lower limb
The patellar ligament separates the kneecap from the lower limb. It connects the bottom of the kneecap to the tibia bone in the lower limb.
All the muscles of the upper limb
flexors
Muscles are in pairs as when one muscle contracts, its pair will relax, and the limb is moved. The reverse happens when the limb is returned to its starting position. Muscles can pull, but they can't push.
The muscle is, Lattisimus dorsi, connected with upper limb at the bicipital groove and with lower limb at illiac crest.
Lower limb bones are attached to the axial skeleton by the pelvic bones, specifically the sacrum which connects to the hip bones to form the pelvis. This connection is important for weight-bearing and locomotion.
The radial nerve supplies the muscles of the arm and forearm and and is also the sensory nerve for the upper limb. It therefore helps in the movement of the upper limb and is also partly responsible for sensory feeling in part of the arm, forearm and hand.
