Анатомия височно-нижнечелюстного сустава - meduniver.com

Summary

The video, hosted by Vitaliy Sinelnikov on the 'Smart Medic' project, explores the anatomy of the temporomandibular joint (TMJ) and its ligaments. It details the structure and function of the joint, which is formed by the mandible's head and the temporal bone. The TMJ allows for a variety of movements such as vertical, sagittal, and transverse motions. The video also discusses the joint's articular disc, its capsule, and various ligaments like the lateral, stylomandibular, and sphenomandibular ligaments, which control and limit the joint's movements.

Takeaways

• 🦷 The video script discusses the anatomy of the temporomandibular joint (TMJ).
• 🔎 The script is part of a project called 'Smart Medic' and is supported by meduniver.com.
• 👥 The speaker is Vitaly Sinelnikov, who is explaining the topic.
• 🗣️ The temporomandibular joint is a complex joint that allows for various types of movement, including vertical opening and closing of the mouth, sagittal movement, and translational movement.
• 👅 The joint is paired, meaning both sides work together and isolated movements on one side are not possible.
• 🦴 The joint is composed of the head of the lower jaw (capitulum) and the mandibular fossa, along with a condylar process and a tubercle.
• 🧬 The articular disc is made of fibrous connective tissue and helps to ensure proper alignment of the joint surfaces.
• 🔄 The joint capsule encloses the bony elements and limits the range of motion of the joint.
• 🔗 The lateral ligament (ligamentum laterale) helps to limit the side-to-side movements of the lower jaw.
• 🔄 The sphenomandibular ligament restrains the forward movement of the lower jaw.
• 🔄 The stylomandibular ligament limits the side-to-side and vertical movements of the lower jaw.

Q & A

What is the name of the speaker in the video?

The speaker's name is Vitaliy Sinelnikov.

What is the main topic of the video?

The main topic of the video is the anatomy of the temporomandibular joint (TMJ).

What is the website that supported the creation of the video?

The website that supported the creation of the video is meduniver.com.

What type of joint is the temporomandibular joint?

The temporomandibular joint is a complex, combined joint that allows for both hinge and gliding movements.

What are the different types of movements the temporomandibular joint allows?

The temporomandibular joint allows for vertical opening and closing of the mouth, sagittal movement (forward and backward), and lateral shifting from side to side.

What is the function of the articular disc in the temporomandibular joint?

The articular disc in the temporomandibular joint provides a more precise joint articulation and divides the joint space into two separate compartments: the upper and lower joint spaces.

What is the structure of the head of the lower jaw (capitulum mandibulae)?

The head of the lower jaw, or capitulum mandibulae, is an oval-shaped condyle that is elongated in the transverse direction and has an articular surface adjacent to the articular disc.

What is the role of the lateral ligament (ligamentum laterale) in the temporomandibular joint?

The lateral ligament restrains lateral movements of the lower jaw and helps to limit the range of motion of the joint.

What is the function of the sphenomandibular ligament?

The sphenomandibular ligament restrains the forward movement of the lower jaw.

What is the purpose of the articular capsule in the temporomandibular joint?

The articular capsule encloses the bony elements of the temporomandibular joint and helps to stabilize it.

How does the video conclude?

The video concludes with a call to action for viewers to be smart in medicine and to develop together with the project, Smart Medic.
