The life study Male Figure Lifting His Right Arm, Side View, right, shows a man raising his arm to expose the muscles more clearly. Between the rich outer edge of the latissimus dorsi and pectoralis major appear some small riblike forms that are the partly exposed shapes of the serratus anterior. Iliocostalis cervicis - extends from the angle of ribs 3-6 until the transverse processes of C4-C6 vertebrae. Semispinalis thoracis - originates from the transverse processes of vertebrae T6-T10 and inserts onto the spinous processes of vertebrae C6-T4. Small veins, called venules, leave from capillaries and gradually increase their lumen on the way to the heart to end as veins. There is a certain histological difference between arteries and veins, but their main functional difference reflects the direction in which they conduct blood: the arteries convey blood from the heart to the periphery, whereas the veins convey blood from the periphery to the heart.

Torso | anatomy | Britannica

The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular components of the body. The external oblique begins on the lower eight ribs (ribs 5 through 12) and inserts into the iliac crest of the pelvis, the inguinal ligament, and the aponeurosis of the external oblique and linea alba. When the external oblique contracts, it helps bend the torso in a forward direction (flexion) as well as sideways (lateral flexion). It also helps move the torso in a twisting action (rotation). The flank pad portion can stretch or compress, especially when the torso bends at the side in a dynamic way. Rectus abdominis, external abdominal oblique, internal abdominal oblique, transversus abdominis, pyramidalis, quadratus lumborum

Rotatores brevis - originates from the transverse processes of vertebrae T2-T12 and inserts onto the laminae/spinous process of a vertebra one level above its origin.

Now that we have a better understanding of the differences between male and female torsos, let's move on to the next section and explore how the anatomy female torso plays a role in posture and movement. 4. Posture and Movement: The Role of Anatomy Female Torso Spinalis thoracis - originates from the spinous processes of T11-L2 and attaches onto the spinous processes of T2-T8.
