Human Skeleton with Internal Organs & Muscles

Quick Answer: The Human Skeleton with Internal Organs & Muscles is a combined anatomy model that shows the bony skeleton together with muscles and the organs of the trunk. A skeleton with organs and muscles lets students see how bones, muscles and viscera fit together in one body instead of studying each system alone.

Placing the Organs Against the Skeleton

Physical examination depends on knowing which organ lies under which bone, and a combined model shows those relationships directly. The heart sits behind the sternum, tilted so its apex points down and to the left, near the fifth intercostal space. The liver fills the space under the right lower ribs, the spleen tucks under the left ribs further back, and the stomach lies in the upper left of the abdomen below the diaphragm. The tops of the lungs rise slightly above the clavicles, a point anaesthetists and surgeons keep in mind when working at the base of the neck.

The back of the trunk has its own landmarks. The kidneys lie against the posterior abdominal wall at about the level of the twelfth thoracic to third lumbar vertebrae, the right one slightly lower because the liver sits above it. The urinary bladder rests behind the pubic symphysis, and the pelvis cradles the lower bowel and, in females, the uterus. Where muscles are shown, students can follow how the abdominal wall and back muscles enclose the organs and how limb muscles cross the joints.

Combined models with this kind of title are often built with muscles on one half of the body and the bare skeleton on the other, and with organs that lift out of the trunk. The listing does not say which organs are included, which side carries muscle, whether parts are removable or what size the figure is, so these points need confirming. For bone-only teaching, the economy skeleton is a simpler alternative.

Teaching With a Combined Model

• Introducing physical examination: where to listen to the heart and where to feel for the liver edge
• Linking bone landmarks to organ positions in nursing and paramedical anatomy
• Senior secondary lessons that bring the skeletal, muscular, digestive and circulatory systems together
• Explaining to first-aid students why rib fractures can injure the liver, spleen or lungs

Specifications

Care of a Multi-System Model

• Lift any removable organs out one at a time and return them to the same place, so fixing pegs and magnets are not strained.
• Keep the skeleton with organs and muscles covered when not in use; dust settles in the recesses around organs.
• Clean painted muscle and organ surfaces with a dry or barely damp cloth, never solvents.
• Move the model by its base or stand, with loose organs removed first.

Why Choose LabEquip

Medical colleges, nursing schools and senior secondary schools buy a combined model when one display needs to cover several body systems at once. LabEquip lists it among the anatomy models in Biology Lab Products; send questions about the organ set and dimensions through the contact page.

Frequently Asked Questions

What does a skeleton with organs and muscles teach that a plain skeleton cannot?

It shows how the soft tissues sit on and inside the bony frame, so students learn which organ lies under each rib or vertebra and how muscles cross joints. A plain skeleton teaches bone names and joints only.

Where does the heart lie relative to the ribs and sternum?

It lies behind the sternum and the left costal cartilages, with the apex pointing down and to the left, usually near the fifth intercostal space in line with the middle of the left clavicle.

Why does the right kidney sit lower than the left?

The liver occupies a large space on the right side above the kidney and pushes it down slightly, so the right kidney usually lies a little lower than the left.

Can the organs be taken out of the model?

On many combined models the heart, lungs, stomach, liver and intestines lift out for closer study, but designs differ. The listing does not describe the organ set, so confirm it when you enquire.

Is this model suitable for schools or only for medical colleges?

Both can use it. Schools use it to show how body systems fit together, while medical, nursing and physiotherapy courses use it to link surface landmarks with the organs underneath.

Why can a broken lower rib be dangerous?

The lower ribs cover the liver on the right and the spleen on the left. A sharp fracture there can tear these organs and cause internal bleeding, which is why rib injuries are assessed carefully.
