Ligament & Meniscus. Related topic Background Each knee has two menisci. They are commonly called âthe cartilageâ, although this is not strictly accurate. There is one on the medial (inner) side of the knee and one on the lateral (outer) side of the knee. They are C, or crescent shaped, and serve to cup the femur as it sits on the tibia to improve the congruity of the joint.
expiratory reserve volume. Type:Term. Definitions. 1. the maximal volume of air (about 1000 mL) that can be expelled from the lungs after a normal expiration.
In addition to the amount of air that could be inspired at rest, the lungs are capable of accommodating an additional amount of air during a deep inspiration. This amount of air that can be inhaled in addition to the tidal volume is known as the inspiratory reserve volume (IRV). Similarly, in a deep and forceful expiration, the lungs are capable of exhaling a volume which is in excess to the tidal volume and the inspiratory reserve volume.
