Is the sternocleidomastoid named for its origin and insertion?
Yes! It originates at the sternum, and the medial portion of the clavicle, and inserts into the mastoid process.
What type of joint is the xiphisternal joint?
the joint is a symphysis and is the region where the body of the sternum articulates with the xiphoid process
Name the depression on the ulna into which the humerus inserts?
Trochlear notch
What type of joint is the sternum?
There are two articulations: the manubriosternal (sternomanubrial) and xiphisternal (xiphisternal)joints.The manubriosternal joint is between the manubrium and the body of the sternum.The sternal angle indicates the manubriosternal joint. In adults this is a secondary cartilaginous joint (symphysis).Xiphisternal (xiphosternal) joints are between the xiphoid process and body of the sternum is a primary cartilaginous joint (synchrondrosis) and these bones are united by hyaline cartilage. By age 40 this joint has ossified.
What is erector spinae activity?
The erector spinae is actually a group of three long postural muscles; iliocostalis, longissimus and spinalis. Their actions are pretty much the same. Iliocostalis is the most lateral of the group. Its origin is the thoracolumbar aponeurosis and ribs one through twelve. It inserts on the transverse processes of lumbar vertebrae one through three, all twelve ribs and the transverse processes of the lower cervical vertebrae. In other words, it begins on the lower vertebral column, arcs outward across the ribs where it has both origins and insertions, and arcs back inward at the lower neck. The long tendons of iliocostalis extend laterally beneath the scapula. It allows unilateral lateral flexion and bilateral extension of the spine. Longissimus, the middle muscle and (as its name suggests) longest of the group, originates on the thoracolumbar aponeurosis and the transverse processes of the thoracic vertebrae one through five. It inserts on ribs four through twelve and the transverse processes of the cervical vertebrae ending at the mastoid process. Longissimus is thick and along with iliocostalis it makes a visible mound along the spine. As mentioned earlier, this muscle's cross sectional area, its thickness, tells you that it is very powerful. Its actions are the same as iliocostalis, but unlike the rest of the group, it has action on the neck as well. Spinalis is the smallest and most medial of the group, lying within the lamina groove. Unlike the rest of the group whose origin is inferior to its insertion, it originates superiorly; at the ligamentum nuchae, the spinous process of cervical vertebra 7, and the spinous processes of the lower thoracic and upper lumbar vertebrae. It inserts at the spinous processes of cervical vertebrae two through seven and the spinous processes of the upper thoracic vertebrae.
What muscle originates on scapula and proximal humerus and inserts on olecranon process?
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
What muscle originates on the distal anterior humerus and inserts onto the coronoid process of the ulna to cause arm reflexion?
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
Is the sternocleidomastoid named for its origin and insertion?
Yes! It originates at the sternum, and the medial portion of the clavicle, and inserts into the mastoid process.
What is origin and insertion points of the corachobrachialis muscle?
It originates from the tip of the coracoid process of scapula (just beside the short head of biceps) and inserts about midway in the medial side of the humerus, in a very faint prominence.
What type of joint is the xiphisternal joint?
the joint is a symphysis and is the region where the body of the sternum articulates with the xiphoid process
What inserts on the coronoid process of the mandible?
The insertion of the temporalis muscle is on the coronoid process of the mandible.
What is the origin of biceps brachii?
The bicep brachii originates on the scapula. As the "bi" prefix of it's name suggests, it has two heads. One originates from the coracoid process of the scapula, and the other from the supraglenoid tubercle of the scapula.
What is it called when a process where a scientist inserts a new gene into an organisms DNA?
The process is called Genetic Modification
Does the biceps brachii muscle originate or insert on the humerus?
It inserts onto the humerus. It originates from the coracoid process of the scapula. There are 2 parts - Long head and short head. The long head is connected to the coracoid process by a tendon that comes up between the tubercules of the humerous. The short head is connected directly to the humerus.
Name the depression on the ulna into which the humerus inserts?
Trochlear notch
What is a process that inserts variable information into a document to produce a customized document?
Mail Merge.
What process a proposed law originates in the State legislature but it can still be voted on by ordinary citizens?
initiative.
