Anatomy of the Heart

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Contact Angle

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Contact-dependent Signaling

Contact-dependent Signaling

Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
Gap Junctions
In animal cells, gap junctions are formed...

Anatomy of the Circulatory System

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Anatomy of the Eyeball

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Background:

Stereoscopic virtual reality (VR) aids clinicians in understanding 3D anatomical models and spatial relationships.
Limited non-contact input devices exist for controlling 3D models in sterile operating room environments.

Purpose of the Study:

To present a cost-effective VR application for stereo display of 3D anatomical models with non-contact interaction.
To enable intuitive manipulation and exploration of complex anatomical structures in a sterile surgical setting.

Main Methods:

Integrated hand gesture recognition (Leap Motion) and voice interaction (Bing Speech, Aitalk) for non-contact control.
Developed a local database for anatomical terminology to support speech recognition accuracy.
Evaluated system efficiency and usability with ten participants comparing it to conventional interaction methods.

Main Results:

The proposed VR system demonstrated greater efficiency compared to common interactive methods.
Participants found the system feasible and practical for use in sterile environments.
Non-contact interaction using gestures and voice significantly improved the user experience.

Conclusions:

The developed VR system offers a practical and efficient solution for non-contact interaction with 3D anatomical models in sterile surgical fields.
This technology has the potential to enhance surgical training, planning, and intraoperative guidance.
Further research can explore integration with other surgical technologies for a comprehensive virtual surgical environment.
