Semispinalis Muscle Anatomy a group of three muscles belonging to the transversospinales. These are the semispinalis capitis, the semispinalis cervicis, and the semispinalis thoracis. Origin Cervical region: made up of seven vertebrae in the neck (C1-C7) The thoracic region: is made up of twelve vertebrae between the neck and lower back (T1-T12) Insertion The semispinalis…
Rectus capitis posterior major muscle Anatomy arises by a pointed tendon from the spinous process of the axis, and, becoming broader as it ascends, is inserted into the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately below the line. origin : Spinous process of the…
Rectus capitis posterior minor muscle Anatomy arises by a narrow pointed tendon from the tubercle on the posterior arch of the atlas, and, widening as it ascends, is inserted into the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum, and also takes some…
Obliquus capitis superior muscle Anatomy a small muscle in the upper back part of the neck and is one of the suboccipital muscles and part of the suboccipital triangle. Origin Lateral mass of atlas. Insertion Lateral half of the inferior nuchal line. Nerve Supply Suboccipital nerve. Blood Supply The obliquus capitis superior muscle and the…
Scalene Posterior Muscle Anatomy The scalene muscles are three paired muscles (anterior, middle, and posterior), located in the lateral aspect of the neck to the floor of the posterior triangle of the neck. a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. The posterior…
Introduction: knee joint is the largest and most complex joint of the body. The knee is one of the largest and most complex joints in the body. The knee joins the femur to the tibia. The smaller bone that runs alongside the tibia and the patella are the other bones that make the knee joint….
The scalenus medius muscle is one of the three scalene muscles located in the lateral neck region. It lies deeper than the anterior scalene and superficial to the posterior scalene. Scalene medius Muscle Anatomy The largest and longest muscle in the scalene group of lateral neck muscles is the middle scalene, also known as scalenus…
Anatomy of Scalene Anterior Muscle Scalene anterior Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene. It is located deeply just behind the Sternocleidomastoid muscle. The brachial plexus and subclavian artery runs between the anterior and middle scalene muscles. This provides an important anatomical location for anaesthetics…
Introduction Scalene Muscle is a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. The cervical tract is laterally positioned and the scalene muscles are deep. Because the brachial plexus and the cervical plexus are involved in their function, their innervation is complex. Their functions…
The Rectus Capitis Lateralis is one of the small suboccipital muscles located in the upper neck region at the back of the head. It is part of a group of four muscles known as the suboccipital muscles. These muscles are responsible for various movements and stabilizing the head and neck. Rectus capitis lateralis muscle Anatomy…
