Human Model – Muscle on Board, Small

Quick Answer: The human muscle model on board, small, is a compact relief of the human figure showing the superficial skeletal muscles, mounted on a board. It is used in biology, physical education and nursing lessons to teach muscle names and positions and how muscles work in pairs to move joints.

Reading the Muscles on a Board Relief

A muscle model on board presents the body’s surface muscles in relief, typically on a figure in front view, although whether this small board shows the front only or the back as well should be confirmed. Because it lies flat, it works well on a desk for small groups or on a wall beside a skeleton chart. The deeper layers of muscle are not usually visible on a relief of this kind.

Muscle names become far easier once students see how they are formed. Many describe shape, such as the deltoid, meaning triangular, and the trapezius; others give location, such as the tibialis anterior on the front of the shin; others count heads, as in biceps and triceps, or give action, as in the flexors and extensors of the forearm. Pointing to each muscle on the board while decoding its name helps the vocabulary stick.

Skeletal muscles can only pull, so they work in antagonistic pairs: when the biceps contracts to bend the elbow the triceps lengthens, and to straighten the arm the triceps contracts while the biceps lets go. The same pattern appears at the knee with the quadriceps and hamstrings. Each muscle attaches by tendons to a fixed origin and a moving insertion, and students can use the board with the human skeleton poster to see which bones those tendons reach.

Specifications

Care & Handling

• Lay the muscle model on board flat or hang it securely; do not lean it against a wall where it can slide and chip at the edges.
• Dust with a soft brush, since the fine grooves between muscles collect dust.
• Wipe painted areas with a barely damp cloth only.

Applications

• Learning the names and positions of the major surface muscles
• Physical education and sports science lessons on the muscles used in movement
• Explaining antagonistic pairs, origins and insertions
• Revision stations and labelling quizzes in biology and nursing

Why Choose LabEquip

Physical education teachers and biology departments often buy small muscle boards so several groups can work at once. LabEquip offers it among its biology lab products; send the number needed through the LabEquip contact page.

Frequently Asked Questions

What does antagonistic pair mean?

It means two muscles that produce opposite movements at the same joint. While one contracts, the other relaxes, as with the biceps and triceps at the elbow.

Why can muscles only pull?

Muscle fibres shorten when they contract but cannot push. A second muscle on the opposite side of the joint is needed to move the bone back.

What is the difference between origin and insertion?

The origin is the attachment that usually stays fixed during a movement. The insertion is on the bone that moves when the muscle contracts.

How are muscles named?

Names often describe shape, such as deltoid, location, such as tibialis anterior, number of heads, such as biceps, or action, such as flexor. Knowing these clues makes the names easier to remember.

Does the board show deep muscles?

A relief of this kind normally shows the superficial layer only. Deeper muscles are taught with layered models, dissections or charts.

Which muscle types are there in the body?

Skeletal muscle, which moves the skeleton and is shown on this board; smooth muscle in the walls of organs such as the gut; and cardiac muscle in the heart.
