Soft tissues of the back Flashcards
Bounded by the upper border of the latissimus dorsi, the lateral border of the trapezius, and the medial border of the scapula.
Triangle of Auscultation
What formed the floor of Triangle of Auscultation?
rhomboid major
Formed by the iliac crest, latissimus dorsi, and posterior free border of the external oblique abdominal muscle
Lumbar Triangle (of Petit)
What formed the floor of Lumbar Triangle (of Petit)?
internal oblique abdominal muscle
The site where breathing sounds can be heard most clearly using a stethoscope invented by Laennec in 1816
Triangle of Auscultation
It may be the site of an abdominal hernia.
Lumbar Triangle (of Petit)
Invests the deep muscles of the back, having an anterior layer that lies anterior to the erector spinae and attaches to the vertebral transverse process, and a posterior layer that lies posterior to the erector spinae and attaches to the spinous processes.
Thoracolumbar (Lumbodorsal) Fascia
Very strong fibrous tissue in posterior lower back
Thoracolumbar (Lumbodorsal) Fascia
Serves as an attachment of the latissimus dorsi, internal oblique muscle and transverse abdominis muscles
Thoracolumbar (Lumbodorsal) Fascia
Arises from the thyrocervical trunk of the subclavian artery and divides into the superficial and deep branches
Transverse Cervical Artery
Arises from the external carotid artery, runs deep to the sternocleidomastoid muscle, and lies on the obliquus capitis superior and the semispinalis capitis.
Occipital Artery
Consists of cranial portion that joins the vagus nerve and a spinal portion that runs deep to the sternocleidomastoid, lies on the levator scapulae, and passes deep to the trapezius
Accessory Nerve
what do the Accessory Nerve innervate?
sternocleidomastoid(SCM)
trapezius muscles
Derived from the ventral primary ramus of the fifth cervical nerve, runs along with the deep branch of the transverse cervical artery, and supplies the rhomboid major and minor and levator scapulae muscles
Dorsal Scapular Nerve (C5)
What does the Dorsal Scapular Nerve (C5) innervate?
rhomboid major and minor
levator scapulae muscle
