The objective of the virtual lab on bones consisted of identifying the major bones of the human body. We had to place the major bones of the body in the correct anatomical position. The key terms included the axial skeleton which includes the skull and the bones that support it, such as, the vertebral column, ribs, and sternum. The appendicular skeleton includes the bones of the limbs and the structures that support them such as, the scapula and pelvic bones. It is also noted that where two bones meet is called a joint.
This study examined the differences in articular surface morphology of caudal vertebrae between prehensile and non-prehensile tailed primates. Articular surface is skeletal surface, which includes bone and cartilage, that makes contact with other skeletal surface as part of a joint. Variation in the morphology of articular surface can confer a greater capacity for mechanical loading, which is required for prehensile primates as they often use their tails to suspend their entire weight during locomotion. In this experiment, it was hypothesized that articular surface area and curvature in caudal vertebrae could be used to distinguish between prehensile and non-prehensile tails. The results showed that articular surfaces found in both proximal and distal regions were greater in prehensile tailed primates, in comparison to primates that were non-prehensile tailed.
The location of the occipital lobe can be seen in the diagram located in the TBI article (marked as Exhibit #8). However, neither of these were present. Instead, we find an open wound on the scalp at the back of Skyler’s head. This is consistent with an impact to a hard surface like the concrete walkway where Skyler was found lying. Next, from that initial back of the head impact, the brain is thrown forward into the skull, causing the contusions to develop at the frontal lobe.
Background Research Teeth come in different shapes and sizes and everyones ' teeth are different. However all teeth have a few things in common- they all have three main layers; Enamel, Dentin, and Pulp. Enamel is the very hard protective shell on the visible part or crown of your tooth. It can withstand chewing and biting but is brittle and can chip/break easily. Dentin consists of a substance that is similar to bone, it is underneath the enamel and gives your teeth their color.
The order primate is divided into two distinct subcategories consisting of prosimians and anthropoids. Prosimians share unique physical characteristics that separate them from other primates, but are displayed within other mammals. Therefore those distinctive traits are commonly referred to as primitive
Introduction The evolution of man has always been a controversial topic. However, no matter what your beliefs are the fact is that man evolved from primates. There is very credible fossil evidence to back this up. Fossils allow us to dig deeper into our past and give us an understanding of what life was like for our ancestors. Particularly, I believe that fossils of our ancestors show that we had to develop bipedalism because of natural selection and environmental factors.
There were two major morphological shifts that occurred during the evolution of bipedalism: reduction in the iliac height and relatively broad sacral alae (Machnicki et al. 2015). Bipedalism allowed modern humans to have iliac blades that are shorter and reoriented so they curve around the side of the body facing laterally and flaring outward (Gruss and Schmitt 2015). This morphology produced the bowl shape of the modern human pelvis. In comparison, non-primates have tall iliac blades, flat plates, and are oriented in the coronal plane which divides the body into dorsal and ventral parts.
Over the years different methods have been proposed for age estimation via human biological characteristics. Among the various methods proposed, Gustafson’s morpho-histologic approach is most popularly used in estimating age using teeth.9 Studies using Gustafson’s six parameters found that translucency of dentin was best suited for age estimation when used indivisually.10 Tomes was the pioneer to describe dentin translucency. He showed that translucency is the result of the consolidation of the dentinal tubules and it was noticed by him that if the air in the dentinal tubules is replaced by water, the translucency of the tooth increases.9 Czermak was of the opinion that various types of translucency arose due to equalization of the normally different refractive indices of the tubules and of the calcified dentine
The middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes. The ossicles were given their Latin names for their distinctive shapes; they are also referred to as the hammer, anvil, and stirrup, respectively. 6. Describe the factors that contribute to sound localization. Sound localization refers to a listener 's ability to identify the location or origin of a detected sound in direction and distance.
Especially if there were people that were looking for her. I’d liked to use both constructing the face onto the skeleton without the artist having seen photographs of the once living person or reconstructing the face onto a plaster model of the skull. By doing these tests, we can learn, what ethnicity the person was, what they looked like, how tall they were, and what gender they were. With this information, one can piece everything together and get an extremely close idea of the characteristics the being
