The ulna is a forearm bone, not a component of the wrist (carpus).
The left and right brain hemispheres are connected by a wide band of nerve fibers called the corpus callosum, which facilitates communication between them.
One bone in the appendicular skeleton—more precisely, the upper limb—is the humerus.
The forearm's medial side is home to the ulna and its lateral side to the radius.
The scapula can move in many directions, such as rotation, retraction, depression, and elevation, thanks to the trapezius muscle.
The hip joint is formed by the femur articulating with the acetabulum of the hip bone, which is made by the pubis, ischium, and ilium.
The hormones glucagon and insulin, which control blood sugar levels, are secreted by the pancreas.
The pectoral girdle, not the pelvic girdle, contains the scapula.
The diaphragm is the main structure innervated by the phrenic nerve, a spinal neuron that arises from the cervical nerves (C3–C5).
