1、 Model usage:
The eye anatomy model teaching instrument of Ningbo Kaidi Science and Education Instrument Co., Ltd. is a visual teaching tool suitable for secondary schools and tertiary hospitals to teach the structure of the eye during human anatomy teaching.
2、 Model structure: general education instrument
1. The anatomy model of the eyeball in this biology teaching instrument is a human eye structure model magnified six times, which can be disassembled and placed on a base.
2. The eyeball wall is horizontally cut through the anterior and posterior poles, showing the three layers of the eyeball wall: outer membrane, middle membrane, and inner membrane.
2.1 Outer membrane: showing the cornea (removable) and sclera.
2.2 Median membrane: shows iris (removable), ciliary body, and choroid.
2.3 Endometrium: Show the blind part of the retina and the optic disc and macula of the retina.
3. Disassembling device: Both the crystalline lens and vitreous body can be disassembled.
4. Eyeball muscles: superior rectus muscle, inferior rectus muscle, medial rectus muscle, lateral rectus muscle, superior oblique muscle, and inferior oblique muscle.
5. Indicating ocular blood vessels and optic nerves
5.1 Ocular vessels: Branches of the ophthalmic artery include the muscular artery, central retinal artery, nasal superior and inferior retinal arterioles, and temporal superior and inferior retinal arterioles; Indicate the superior ophthalmic vein, inferior ophthalmic vein, and their branches.
3、 Model use and storage:
1. The anatomy model of the eyeball in this biology teaching instrument is made of high-quality synthetic plastic, which is lightweight, sturdy, and non deformable. It is suitable for use and storage in environments ranging from 0 ℃ to 40 ℃.
2. When teaching the structure of the eyeball refractive device, first remove the eyeball wall to see through its internal structure. At the same time, the cornea, iris, crystalline lens, and vitreous body can be taken one by one to teach their morphology and function separately.
3. After using the anatomy model of the eyeball in biology teaching instruments, dust prevention and removal treatment should be carried out. The storage site should be dry, ventilated, and avoid direct sunlight to ensure that the model has a bright color and is durable.
