Lower Back Muscles Anatomy Artofit Learn anatomical details of the lower back muscles, so you can draw them. full lesson at proko anatomyin this special pirate anatomy lesson, we’ll. Back anatomy. 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 back functions are many, such as to house and protect the spinal cord, hold the body and head upright, and adjust the movements of the upper and lower limbs.
How To Draw The Back Muscles With The Arms Raised Youtube 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 are therefore classed as extrinsic muscles. It’s crucial to study muscle origin, insertion, function, antagonist, and form to master muscles for figure drawing. when a muscle contracts, it pulls the insertion closer to the origin. an antagonist is needed, however, to stretch them back out. muscles that have similar functions are often grouped when they’re relaxed. 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. the extrinsic (superficial) back muscles, which lie most superficially on the back. The back anatomy is only slightly simpler than the front of the torso. the main muscles of the back can be grouped easier and thus it’s a more manageable task to memorize their locations and relationships. the range of motion, contortions and wedging of shapes are a bit less convoluted as well. the main hurtle in this tutorial will be learning how the scapula or shoulder blade relates with.

Attachments: arises from the common tendinous origin, and attaches to the costal angle of the ribs and the cervical transverse processes. innervation: posterior rami of the spinal nerves. actions: acts unilaterally to laterally flex the vertebral column. acts bilaterally to extend the vertebral column and head. It is the most superficial of all the back muscles. attachments: originates from the skull, ligamentum nuchae and the spinous processes of c7 t12. the fibres attach to the clavicle, acromion and the scapula spine. innervation: motor innervation is from the accessory nerve. it also receives proprioceptor fibres from c3 and c4 spinal nerves.
