2023年11月3日 · Attachments, innervation and functions of the superficial muscles of the back. The back is the body region between the neck and the gluteal regions. It comprises the vertebral column (spine) and two compartments of back muscles; extrinsic and intrinsic.

The muscles of the back can be arranged into 3 categories based on their location: superficial back muscles, intermediate back muscles and intrinsic back muscles. The intrinsic muscles are named as such because their embryological development begins in the back, oppose to the superficial and intermediate back muscles which develop elsewhere and ...

2023年2月15日 · There are three different groups of muscles in the back. These are called the superficial, intermediate, and intrinsic muscles. The sections below cover these in more detail. The superficial,...

The muscles of the back can be classified as either deep, intermediate and superficial. Each of these 3 classes have distinct roles in support, movement and/or aiding in specialised functions such as in inspiration/expiration. In this section, learn more about the vertebral column, the muscles of the back and the spinal cord.

While it is difficult to count the exact number, the human back muscles can be divided into 3 groups or layers based on their location and functions in the region — (1) superficial or extrinsic, (2) intermediate, and (3) deep or intrinsic. Find out about all the muscle groups within these three layers: 1. Superficial or Extrinsic Muscles (5)

2023年11月1日 · Back muscles are classified into three types: superficial, middle, and deep: Superficial – linked with shoulder movements. Intermediate – related to thoracic cage movements. Deep – linked with spinal column movements. Because deep muscles develop embryologically in the back, they are referred to as intrinsic muscles.

2024年12月31日 · It is primarily composed of the vertebral column (spine), muscles, nerves, blood vessels, and overlying skin. The back provides structural support and protection for the spinal cord while serving as the attachment point for muscles that facilitate posture and movement. The back is located on the posterior aspect of the body.

2023年11月3日 · Attachments, innervation and functions of the superficial muscles of the back. The muscles of the back are a group of strong, paired muscles that lie on the posterior aspect of the trunk. They provide movements of the spine, stability to the trunk, as well as the coordination between the movements of the limbs and trunk.

2024年1月15日 · The layers of the back comprise the skin, subcutaneous tissue, superficial (extrinsic) and deep (intrinsic) back muscles, the posterior portion of the ribs, and the vertebral column housing the spinal cord and surrounding meninges.
