Minor Losses in Pipes01:25

Minor Losses in Pipes

2.0K
In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...

Classification of Skeletal Muscle Fibers01:48

Classification of Skeletal Muscle Fibers

59.6K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Muscles of the Eye01:20

Muscles of the Eye

4.5K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Muscles that Move the Head

6.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Muscles of the Abdomen01:21

Muscles of the Abdomen

3.6K
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...

Muscles that Move the Arm01:31

Muscles that Move the Arm

4.9K
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...

Summary

The psoas minor muscle (PMM) was found in 60% of Bulgarian cadavers, a higher frequency than in India but similar to Brazil. Morphometric analysis revealed shorter PMM in Bulgarians compared to other populations.

Area of Science:

  • Anatomy
  • Human Anatomy
  • Musculoskeletal System

Background:

  • The psoas muscle group, part of the posterior abdominal wall, includes the psoas major, minor, and tertius.
  • The psoas major is an obligatory muscle, present in all individuals.
  • The psoas minor muscle (PMM) originates from the thoracic and lumbar vertebrae and inserts into the iliopectineal eminence, contributing to limited lumbar spine flexion.

Purpose of the Study:

  • To determine the frequency of the psoas minor muscle in the Bulgarian population.
  • To conduct morphometric analysis of the psoas minor muscle in Bulgarian cadavers.

Main Methods:

  • Anatomical dissection of 10 cadavers at the Medical University, Varna, Bulgaria.
  • Measurement of psoas minor muscle length, width, and circumference.
  • Descriptive statistical interpretation of collected morphometric data.

Main Results:

  • The psoas minor muscle was present in 60% of the studied cadavers (6 out of 10).
  • The muscle was bilateral in 3 cadavers, unilateral left in 1, and unilateral right in 2.
  • Average measurements: length 19.66 cm, width 1.73 cm, circumference 3.48 cm.

Conclusions:

  • The frequency of the psoas minor muscle in the Bulgarian population (60%) is higher than in India (36.67%) and comparable to Brazil (59%) and the US (65.6%).
  • Morphometric analysis indicated a shorter psoas minor muscle in the Bulgarian population compared to other studied populations.
