Human Model – Breast, 2 Parts

Quick Answer: The human breast model, 2 parts, is an anatomical teaching model of the adult female breast that separates into two pieces to reveal its internal structure. It is used in nursing, midwifery and health education to teach the glandular lobes, milk ducts, fatty tissue and supporting ligaments.

Inside the Breast: What the Second Part Reveals

From the outside, a breast anatomy model shows the nipple, the pigmented areola with its small raised areolar glands, and the overall shape of the breast over the chest wall, including the tail of tissue that extends toward the armpit. Removing the second part opens the interior, although which layers are exposed and how the model divides should be confirmed at enquiry.

Inside, glandular tissue is arranged in lobes radiating from the nipple like the segments of an orange. Each lobe contains smaller lobules where milk is produced during lactation, drained by a lactiferous duct that opens at the nipple. Fatty tissue fills the space between the lobes and gives the breast most of its size, and fibrous suspensory ligaments run from the skin to the deep tissues, supporting the breast. Behind it all lie the pectoralis major muscle and the ribs.

Lymphatic drainage is another point nursing courses cover with this model: most lymph from the breast passes to the lymph nodes in the armpit, which is why that area is included in breast awareness teaching. A two-part anatomical model is designed to show structure; practising breast examination by touch is normally done on a soft examination simulator with embedded lumps, which is a different product.

Specifications

Applications

• Teaching breast structure in nursing and midwifery anatomy
• Breastfeeding education, showing where milk is made and how it reaches the nipple
• Breast awareness sessions explaining normal structure and lymph drainage to the armpit
• Secondary biology lessons on mammary glands and lactation

Care & Handling

• Handle the removable part of the breast anatomy model by its edges and lay it on a clean cloth while the interior is studied.
• Clean with a soft cloth and mild soapy water; alcohol can dull the painted ducts and lobes.
• Store both parts together in a covered box.

Why Choose LabEquip

Midwifery schools, nursing colleges and community health trainers use a breast model to explain structure clearly and respectfully. It is available among LabEquip’s biology lab products, as is the female genital organs model for broader reproductive anatomy. Enquire through the LabEquip contact page.

Frequently Asked Questions

What are the main internal structures of the breast?

Glandular lobes made up of smaller lobules, lactiferous ducts that carry milk to the nipple, fatty tissue between the lobes and fibrous suspensory ligaments that support the breast.

What are suspensory ligaments?

They are bands of connective tissue, often called Cooper’s ligaments, running from the skin through the breast to the deeper tissues. They help support the breast’s shape.

Where does lymph from the breast drain?

Most of it drains to the lymph nodes in the armpit, with smaller amounts going to nodes near the breastbone and above the collarbone. This is why the armpit is included in breast awareness.

Can this model be used to practise breast examination?

It is an anatomical model for teaching structure. Hands-on examination practice is normally done with a soft breast examination simulator that contains palpable lumps, which is a separate item.

How does the model help in breastfeeding education?

It shows where milk is produced in the lobules and how the ducts carry it to the nipple. Midwives use this to explain how a baby’s feeding draws milk from the breast.

What is the areola?

It is the ring of darker skin around the nipple. It contains small glands that produce an oily secretion, which protects the skin during breastfeeding.
