High Detail Human Bones
It can be used in anatomy teaching in medical colleges and universities to help students understand the structure and function of human bones more intuitively. It can also be used in medical training, such as orthopedic surgery simulation, rehabilitation training, etc., to provide medical professionals with a reference model for practical operation.
normal red blood cells versus sickle-shaped red blood cells
Sickle cell anemia, also known as sickle cell anemia and sickle cell anemia, is a hereditary hemoglobinopathy. The amino acid glutamic acid at the 6th position of the β-peptide chain is replaced by valine, which forms sickle hemoglobin and replaces normal hemoglobin. The clinical manifestations are chronic hemolytic anemia, predisposition to infection, and recurrent pain crisis causing chronic ischemia leading to organ and tissue damage. Mainly through blood transfusion, drug treatment and other methods of treatment.
Cervical Nerve Medicine 3D Model
The cervical spine (Cervical Spine) is the upper part of the spine that connects the skull to the thoracic spine and consists of seven vertebrae (C1 to C7). Its special structure, both flexibility and stability, is the head movement (such as rotation, pitch) and nerve, vascular access key area.
cardiac conduction system
The cardiac conduction system is the structure in the heart responsible for generating and conducting electrical signals to ensure that the heart beats rhythmically.
Ophthalmoscope, an ophthalmic instrument invented in 1850
The ophthalmic instrument, Helmholtz also known as the ophthalmoscope, was invented in 1850 by the German scientist Hermann von Helmholtz (Hermann von Helmholtz). The main function of this instrument is to allow ophthalmologists to observe the retinal details of the living eye. The ophthalmoscope allows the doctor to see the structures inside the eye by reflecting light that enters the pupil. The invention of this instrument has greatly promoted the development of ophthalmology, allowing doctors to diagnose eye diseases and prevent them. Before Helmholtz invented the ophthalmoscope, doctors could not see the posterior pole of the retina in the eye of a living patient.
Cicada shell specimen
The cicada shell, or cicada slough, is the shell that falls off when the larvae of the cicadae black grasshopper are feathered.

Sweet and salty in nature, cool in nature, and return to the lung and liver. Has a variety of effects, including the evacuation of wind and heat, pharynx open sound, rash and itching, eyesight, wind and spasm. In traditional Chinese medicine, it is often used to treat wind-heat cold, sore throat, mute sound, impervious measles, rubella pruritus, erythematous phallitis, acute and slow convulsed wind, tetanus syndrome, etc. Cicada shell can also be used for children night cry restless.
