IT has three holes for the vertebral foramen and two for the transverse foramina. The thoracic vertebrae have longer and heavier transverse processes and are characterized by their articulating surfaces with the ribs. The lumbar vertebrae have pedicles and laminae that are shorter and thicker than those of other vertebrae, the vertebral foramen is triangular, and spinous processes are short.…

A).Which clue would tell Stefan which scapular surface was anterior and which was posterior? What is the name of the shallow, oval socket of the scapular that Stefan placed next to the humerus? When he pulled out the two bundles, each containing a narrow S-shaped bone. Turning them over in his hands, he quickly decided which was right and which left, then placed each clavicle by its neighboring scapula. In order to determine if a scapula is right or left, orient it so the glenoid fossa (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be superior and anterior. Glenoid cavity is what he place next to the humerus.…
A. Baru is using surface markings to identify the gender of a skull. What two major types of surface markings do bones have? The two major types of surface markings are depressions (or openings) and processes. Depressions and openings form joints or passageways for blood vessels and nerves. Processes form joints or points of attachment for ligaments or tendons.…

ANSWER: Bone brittleness results from a decrease in the rate of protein synthesis and in the production of human growth hormone, which diminishes the production of the collagen fibers that give bone its strength and flexibility. As a result, inorganic minerals gradually constitute a greater proportion of the bone extracellular matrix. Loss of bone mass results from demineralization and usually begins after age 30 in females, accelerates greatly around age 45 as levels of estrogens decrease, and continues until as much as 30% of the calcium in bones is lost by age 70…

Landmarks used in Thoracic spine positioning include the jugular notch which corresponds to level T2 and T3. T1 is about 1.5 inches superior to the level of the jugular notch. The first thoracic vertebra can be located by palpating posteriorly at the vase of the neck for the prominent spinous process of C7, the vertebra prominens. The most frequently used landmark is the level of T7. Anteriorly it is located about 3 to 4 inches inferior to the jugular notch or at the midpoint of the jugular notch and the xiphoid…

Lewis (2014) states “ spinal cord injuries are generally the direct result of trauma that causes cord compression, ischemia, edema, and possible cord transection”(p.1172). The level and degree of injury have a direct relation to the severity of symptoms, with the higher the injury, the more loss of function you have because of the close proximity to the brain stem, medulla, and cervical cord (Lewis, 2014). There are five major mechanisms of injury including hyperextension, flexion, flexion-rotation, extension-rotation, and compression (Lewis, 2014). Complete injury means there is no sensory or motor function below the level of injury. Incomplete injury is a mixed loss of motor and sensory function below the level of injury. The degree varies between sensory and motor loss due to the level of injury (Lewis, 2014). There are three levels of injury, those being cervical, thoracic, and lumbar. Lumbar and cervical injuries are the most common due to movement and increased flexibility (Lewis, 2014). Depending on the degree of injury you may become a paraplegic or a tetraplegia. Paraplegia is a loss of sensation in the trunk and lower limbs due to the thoracic cord in the lumbar spine being damaged (Lewis, 2014). Tetraplegia is paralysis in all four extremities due to the cervical cord being…
