Summary
The superior transverse scapular ligament (STSL) in fetuses shows anatomical variations, particularly in thickness on the left side. These morphometric findings in fetal development may inform future research on the ligament
Area of Science:
- Anatomy
- Morphology
- Developmental Biology
Background:
- The superior transverse scapular ligament (STSL) forms the suprascapular foramen, crucial for the passage of the suprascapular nerve.
- Ossification of the STSL can lead to suprascapular nerve compression and associated symptoms.
Purpose of the Study:
- To describe the anatomical and morphometric characteristics of the STSL in human fetuses.
- To investigate potential differences in STSL dimensions between fetal left and right sides.
Main Methods:
- Dissection of twenty human fetal shoulders (21-33 weeks gestation).
- Precise measurement of STSL length and thickness using a digital pachymeter.
- Comparison of measurements between left and right sides of the body.
Main Results:
- No significant differences in STSL length or extremity thickness between left and right sides.
- The medial extremity of the STSL was significantly thinner on the left side compared to the lateral extremity (P ≤ 0.05).
Conclusions:
- Detailed anatomical and morphometric data of the fetal STSL were established.
- These fetal findings warrant further investigation into the ligament's morphofunctional role and clinical significance.

01:23Muscles of the Shoulder
9.4K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:14Fetal Circulation
5.0K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:18Uterus and Cervix
8.4K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

01:14Cranial Bones: Superior and Posterior View
7.6K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:31Muscles that Move the Arm
5.5K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:21Muscles of the Abdomen
4.7K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...
