Iliac Spine Research Paper

Brachialis - It's attachments are the deltoid tuberosity and coronoid process of unla. When it contracts it causes flexion. It's located close to the endangerment site the antecubital.

Movement of the deltoid begins in the cerebrum of the brain, but more specifically: in the frontal lobe, the premotor cortex is relaying instructions to the primary motor cortex. The primary motor cortex contains the upper motor neurons whose axons will travel down the pyramids of the medulla oblongata and synapse on lower motor neurons in the anterior gray horns of spinal cord segments C5-C6. From there, the ventral rami of spinal nerves C5-C6 form the superior trunk of the brachial plexus, which splits into two divisions. We will follow the posterior division that supplies to extensor muscles. This posterior division then runs into the posterior cord from which the axillary nerve is derived. The axillary nerve’s motor end innervates the deltoid through its neuromuscular junction.

The structure that furnishes the axis for the rotation of the head from side to side is the:

16. In bone structure, the cortex can best be described as which of the following?

Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.

A. Sketch each slide below and describe the tissues and structures you observed on each slide.

Some examples include the following: clavicle, coccyx, femur, fibula, foramen magnum, mandible, maxilla, metatarsals, ossify, phalanges, radius, scapula, sternum, suture, tibia, ulna, and vertebra. All of these terms are associated with the skeletal system. The mandible, maxilla, and foramen magnum are located in the cervical vertebrae. The clavicle, scapula, and sternum are located in the thoracic vertebrae. The lumbar vertebra contains the humerus, ulna, and radius. The coccyx is located in the sacral vertebrae. The femur, fibula, metatarsals, phalanges, and tibia are located in the appendicular skeleton. The sutures are located in the skull. The vertebrae is the backbone of the body. Ossification is the formation of bone. These terms are important in knowing and learning the skeletal system.

It is a modified hinge joint that allows flexion and extension, as well as anterior and posterior gliding and minimal rotation. The bony articulations of the knee include medial and lateral tibio-femoral articulations and a patello-femoral articulation. There is also an articulation between the head of the fibula and the tibia, but the fibula does not bear weight and is not considered part of the knee joint itself. The afore-mentioned articulating surfaces are incongruous, and the stability of the knee relies mostly on the integrity of the supporting muscles and ligaments. The muscles that span the knee are the quadriceps anteriorly, the hamstrings and gastrocnemius posteriorly, and the tensor fascia latae (iliotibial band) laterally (Moore 2014).
