Insights

Researchers detailed the chicken femoral head

Area of Science:

  • Veterinary Anatomy
  • Comparative Vasculature
  • Avian Biology

Background:

  • The vascular supply to the femoral head is crucial for its health.
  • Understanding these vessels aids in studying conditions like osteonecrosis.

Purpose of the Study:

  • To comprehensively evaluate the vascular supply to the femoral head in chickens.
  • To identify previously undescribed arterial branches supplying this region.

Main Methods:

  • Anatomical dissection of 24 hips from 12 Leghorn chickens.
  • Utilized a casting agent to highlight arterial anatomy.
  • Detailed examination of the external iliac and ischiatic arteries.

Main Results:

  • Confirmed existing knowledge of femoral head perfusion.
  • Identified three new arterial branches: acetabular branch of the femoralis artery, lateral retinacular artery, and ascending branch of the middle femoral nutrient artery.
  • These branches directly supply the acetabulum and femoral head.

Conclusions:

  • Precise understanding of femoral head vasculature is established.
  • This knowledge facilitates surgical interventions like vessel ligation.
  • Enables development of a reproducible avian model for femoral head osteonecrosis research.

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
Veins of Lower Limbs01:15

Veins of Lower Limbs

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...
Arteries of the Head and Neck01:26

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
