Superior lobe of the lung

The superior lobe of the lung, also known as the upper lobe, is one of the three lobes found in the right lung, and one of the two lobes in the left lung. It is located in the upper part of the lung, above the horizontal fissure in the right lung, and above the oblique fissure in the left lung.

The superior lobe of the lung is responsible for approximately 45% of the lung's total volume. It contains several bronchopulmonary segments, each of which is supplied by its own bronchus and pulmonary artery.

Superior lobe of the thyroid

The superior lobe of the thyroid, also known as the upper lobe, is one of the two lobes that make up the thyroid gland. It is located above the isthmus of the thyroid, and is typically larger than the inferior (lower) lobe.

The superior lobe of the thyroid is responsible for the production of thyroid hormones, which regulate the body's metabolism.

Superior lobe of the brain

The term "superior lobe" is not commonly used in reference to the brain, but can refer to the uppermost part of certain brain structures, such as the frontal lobe and the parietal lobe. These lobes are involved in a variety of functions, including motor control, cognition, and sensory processing.
