Muscle Anatomy And Physiology Test! Trivia Quiz

Transverse Cervical artery, vein, and subtrapezial nerve plexus are located here. Both innervate the trapezius

Would impinge upon suprascapular nerve causing supraspinatus and infraspinatus to have decreased function. Would have weakness in lateral rotation.

The thoracodorsal nerve and artery innervate the Latissimus Dorsi muscle.

The correct answer is Dorsal Rami. The extrinsic muscles of the back, which include the muscles that move the upper limb, are innervated by the dorsal rami of the spinal nerves. These nerves branch off from the spinal cord and supply the muscles and skin of the back. The ventral rami, on the other hand, innervate the muscles and skin of the anterior and lateral parts of the trunk and limbs. The dorsal scapular nerve and thoracodorsal nerve are specific branches of the dorsal rami that innervate certain muscles in the back.

The outermost layer of a synovial joint is called the articular capsule. This capsule surrounds the joint and provides stability and support. It is composed of dense connective tissue and is responsible for containing the synovial fluid within the joint. The articular capsule also helps to prevent excessive movement and protects the joint from injury.

The internal vertebral venous plexus is located in the epidural space. This space is located just outside the dura mater, which is the outermost layer of the meninges that surround the spinal cord. The internal vertebral venous plexus is a network of veins that runs along the length of the vertebral column and is responsible for draining blood from the spinal cord and surrounding structures. The location of the plexus in the epidural space makes it susceptible to cancer spread from nearby structures, such as the vertebrae or spinal cord.

Can see rhomboid major inside. Upper border is lat. Medial border is the scapula.

The film terminal externum is made up of the dura layer. The dura layer is the outermost and toughest layer of the meninges, which are the protective membranes that surround the brain and spinal cord. It acts as a protective barrier and helps to maintain the shape and structure of the central nervous system. The arachnoid and pia layers are also part of the meninges, but they are not specifically mentioned as making up the film terminal externum. Therefore, the correct answer is dura.

The posterior superior serratus and posterior inferior serratus muscles are innervated by the intercostal nerves. The intercostal nerves are a set of nerves that run along the spaces between the ribs and provide sensory and motor innervation to the muscles and skin of the thorax. In this case, they specifically innervate the posterior serratus muscles, which are responsible for various movements of the ribs during breathing.

The Lower Serratus Anterior muscle is likely related to the pain Lacey is experiencing when trying to stretch her back in a way that depresses her scapula. This muscle is located on the side of the ribcage and attaches to the scapula, helping to stabilize and move it. If this muscle is tight or strained, it can cause pain and discomfort when trying to stretch or move the scapula in certain ways. The other muscles listed (Rhomboid Minor, Latissimus Dorsi, Levator Scapulae) may also be involved in scapular movement and stability, but the Lower Serratus Anterior is the most likely culprit based on the given information.

Levator Scapulae, Rhomboid Major, Rhomboid Minor, LS involved in elevating shoulder girdle- trap would still be able to do some, R major and R minor are involved in shoulder retraction trap is still working to do this, the Lower trap does depression of scapula, Mid and upper trap do an upward rotation.
