Medial branches. The medial branches of the posterior divisions of the upper six thoracic nerves run between the semispinalis dorsi and multifidus, which they supply. They then pierce the rhomboidei and trapezius, and reach the skin by the sides of the spinous processes . The medial branches of the lower six are distributed chiefly to the ...
v. t. e. The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.
The posterior parietal cortex is a portion of the parietal lobe, which manipulates mental images, and integrates sensory and motor portions of the brain. A majority of experiments highlights a role of human posterior parietal cortex in visual working memory and attention. We therefore have to establish a clear separation of visual memory and ...
Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. [1]The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye ...
2) Dorsal ramus of nerve C1-suboccipital nerve 3) Suboccipital venous plexus. The purpose of these muscles is to provide fine motor function in movements of the head. The actions of trapezius, sternocleidomastoid and other larger muscles that move the head are refined by the relatively small suboccipital triangle muscles.
The trapezius muscle (pl.: trapezii) is a surface muscle of back, shown in red above and below. Details. Origin. Medial one-third of superior nuchal line, external occipital protuberance, spinous processes of vertebrae C7-T12, Nuchal ligament [1] Insertion. Posterior border of the lateral one-third of the clavicle, acromion process, and spine ...
The thoracodorsal nerve arises from the posterior cord of the brachial plexus. It is derived from their ventral rami (in spite of the fact that the latissimus dorsi is found in the back) of cervical nerves C6-C8. [1][3] It is derived from fibres of the posterior divisions of all three trunks of the brachial plexus. [4]
The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the " limbic lobe ". The cingulate cortex is made up of an area around the midline of the brain. Surrounding areas include the retrosplenial cortex and the precuneus.
