erector spinae group
Is the quadratus lumborum superficial or deep?
They are deep muscles in the back.
Is multifidus a deep muscle posterior to spine?
The multifidus muscles are deep, intrinsic muscle of the spine. Deep in that it has overlying musculature, intrinsic in that they originate and insert to the spine. The multifidi, along with the rotatores and semispinalis are collective referred to as the transversospinalis muscles given that they orriginate from the transverse processes of the spine & insert on the spinous processes of the spine. The multifidi themselves only span about 2-3 vertebral segments (bones in your back). The transversospinalis group lays deep to the larger erector spinae, which is a midline intrinsic back muscle group.
The dorsal rami of the spinal nerves serves?
Skin and deep muscles of the back.

What are deep muscles called?

What action does the multifidus have in common with the erector spinae?
The Erector Spinae muscle actually consists of three columns of muscles, the Iliocostalis, Longissimus, and Spinalis, each running parallel on either outer side of the Vertebra and extending from the lower back of the skull all the way down to the Pelvis. The multifidus muscle is a series of small, triangular muscle bundles located on either side of the spinal column that make up the 2nd layer of the deep back muscles. Composed of 3 layers total, the deep back muscles are collectively called the intrinsic layer. Yet another name for this group is the transversospinal layer. Above the transversospinal (deep) layer of back muscles is the superficial layer.The superficial layer is also known as the extrinsic muscles or the "erector spinae," or simply the paraspinal muscles. The multifidus stabilizes the spine and helps the erector to move it.
Is the skin superficial to muscles below it?
No, the hypodermis is deep to the dermis. The dermis is superficial to the hypodermis.
Is skin superficial or deep to the muscles below it?
Skin is superficial to muscles. Superficial means above, while deep means below. So muscles are deep to skin and dermis is superficial to muscle tissue.
What is the deep muscle of the thorax that promotes the inspiratory phase of breathing?
The deep muscles of the thorax that promote inhaling are known as the diaphragm muscles. These are the muscles that are activated when a person has good posture and takes a deep breath.
Are bones superficial to muscles?
Bones are deep to muscles. Muscles are superficial to bones.
