Human Torso, Horizontal Shears

Quick Answer: The human torso, horizontal shears, is a torso model cut into horizontal slices, so that each layer shows the body in cross-section at a different level. This horizontal section torso model is used in anatomy, radiography and medical courses to teach how organs appear in cross-section and to prepare students to read CT and MRI images.

Shears, Slices and Cross-Sectional Anatomy

Shears in this title most likely means sections or slices: the torso is divided by horizontal cuts into layers that can be lifted apart, the model form usually called a cross-sectional or transverse-section torso. Each cut face shows the organs, vessels, muscles and bones at that level, as they would appear if the body were sliced across.

This is the view used by computed tomography and MRI, which display the body as axial slices. Students who can recognise the liver, aorta, a vertebra and the kidneys on a physical slice find it much easier to interpret the same structures in shades of grey on a scan. Working down the model also shows how organs change shape and position: the heart and lungs fill the thoracic levels, the liver and stomach dominate the upper abdomen, and the intestines and kidneys the lower.

The number of slices, the levels at which they are cut and whether the head is included are not given in the title, so radiography programmes may want to compare those levels with their imaging syllabus. For whole-organ study, the conventional torsos in this range, such as the 27 part torso with muscles and open back, are the complement.

Specifications

Applications

• Teaching cross-sectional anatomy in medical and allied health courses
• Preparing radiography and imaging students to read axial CT and MRI slices
• Showing how organ relationships change from the chest down to the pelvis
• Surgical and nursing anatomy where the vertebral level of an organ matters

Care & Handling

• Lift the horizontal slices of the torso one at a time and lay them in order on a padded surface.
• Restack the sections in their original sequence; a small numbered label under each slice helps.
• Clean the cut faces with a dry, soft brush to protect the painted detail.

Why Choose LabEquip

Medical colleges and radiography schools use a sectional torso to bridge textbook anatomy and scan images. The model is supplied through LabEquip’s biology lab products range; the contact page is the place to ask how many sections it has and where the cuts fall.

Frequently Asked Questions

What does horizontal shears mean?

In this listing it describes a torso divided by horizontal cuts into slices, usually called a cross-sectional or transverse-section torso. The word shears appears to be used in the sense of sections.

Why is cross-sectional anatomy taught with models?

CT and MRI images show the body as thin horizontal slices. Seeing the same levels on a physical model helps students recognise organs and their relationships when they later interpret scans.

Which way are CT slices viewed?

By convention, axial slices are viewed as if from the patient’s feet, so the patient’s right side appears on the left of the image. Students often practise this orientation with sectional models.

What can be seen at the level of the upper abdomen?

A slice there typically shows the liver on the right, the stomach and spleen on the left, the aorta and inferior vena cava in front of the vertebra, and the back muscles behind it.

How is this different from an ordinary torso model?

An ordinary torso has organs that lift out whole. A horizontal section torso keeps everything in place and cuts through it, so it shows how organs, vessels and bones lie together at each level.

Who uses a sectional torso?

Medical, radiography, physiotherapy and nursing students, and anatomy departments that teach imaging. It is less common in schools, where whole-organ torsos are usually preferred.
