The rectus abdominis muscle originates on the pubic crest and pubic symphysis and inserts on the cartilage of the 6th and 7th ribs and the xiphoid process. It is responsible for flexing the lumbar spine and compressing the abdominal contents.
iliocostalis.
The pectoralis major is a muscle that does not attach to the ribs or the iliac crest. Instead, it primarily originates from the clavicle and the sternum and inserts into the humerus. Its primary functions include shoulder flexion, adduction, and internal rotation.
A crest is the highest point of a wave where the water level is elevated above the normal level. It is the point where the wave begins to break and move toward the shore.
The muscle is, Lattisimus dorsi, connected with upper limb at the bicipital groove and with lower limb at illiac crest.
In anatomy, a crest refers to a prominent ridge or projection on a bone surface, often serving as a point for muscle attachment. These crests provide structural support and aid in the movement of the associated muscles. Examples include the iliac crest in the pelvis and the crest of the tibia in the lower leg.
Breakers form when the trough (or wave) hits the bottom and rises toward the shore, the crest falls, then the wave breaks up.
The anterior iliac crest serves as the origin for several muscles, primarily the tensor fasciae latae and part of the sartorius muscle. Additionally, it provides attachment for the external oblique muscle and plays a role in the origin of the internal oblique and transversus abdominis muscles. These muscles contribute to various movements of the hip and trunk.
