Выполняющая функция позвоночника и грудной клетки СДЕЛАЙТЕ ПОЖАЛУЙСТА НУЖНО ОЧЕНЬ СРОЧНО!ЗАРАНЕЕ ОГРОМНОЕ СПАСИБО)​

Answer 1

Функции Позвоночника выполняет функцию опоры, защиты спинного мозга и участвует в движениях туловища и головы.

Основная функция грудной клетки – защита внутренних органов. Эта костная структура защищает от механических ударов легкие, сердце, спинной мозг и трахею, а также часть пищевода.

The Function of the Spine and Thoracic Cage

The spine, also known as the vertebral column, and the thoracic cage play crucial roles in the human body. Let's explore their functions in more detail:

1. Spine: The spine is a complex structure composed of individual bones called vertebrae. It serves several important functions:

- Support and Stability: The spine provides structural support and stability to the body, allowing us to maintain an upright posture and perform various movements. - Protection of the Spinal Cord: The spinal cord, which is a vital part of the central nervous system, runs through the vertebral canal formed by the vertebrae. The spine acts as a protective barrier for the spinal cord, shielding it from potential injuries. - Range of Motion: The spine allows for a wide range of motion, enabling us to bend forward, backward, and sideways, as well as rotate and twist our torso. - Weight Bearing: The spine bears the weight of the upper body and transfers it to the pelvis and lower limbs, ensuring proper distribution and balance. - Shock Absorption: The intervertebral discs, located between the vertebrae, act as shock absorbers, cushioning the spine and reducing the impact of everyday movements.

2. Thoracic Cage: The thoracic cage refers to the bony structure that surrounds and protects the thoracic organs, including the heart, lungs, and major blood vessels. It consists of the following components:

- Ribs: The ribs are long, curved bones that form a protective cage around the thoracic organs. There are 12 pairs of ribs, attached to the thoracic vertebrae at the back and the sternum (breastbone) at the front. - Sternum: The sternum is a flat bone located in the center of the chest. It connects the ribs anteriorly and provides support and protection to the underlying organs. - Costal Cartilages: The costal cartilages are flexible connective tissues that connect the ribs to the sternum, allowing for slight movement and flexibility during breathing. - Thoracic Vertebrae: The thoracic vertebrae are the 12 vertebrae in the upper and middle back region that articulate with the ribs. They provide support to the thoracic cage and contribute to its overall stability.

The thoracic cage plays a vital role in protecting the delicate organs within the thoracic cavity, while also providing attachment points for muscles involved in breathing and movement of the upper limbs.

In summary, the spine provides support, stability, and protection to the body, while the thoracic cage safeguards the thoracic organs and facilitates breathing. These structures work together to maintain the integrity and functionality of the human body.
