Activity 1.2.2: Skeleton Scavenger Hunt Introduction Throughout the Human Body Systems course‚ you will explore the many functions of the skeletal system. Bones‚ cartilage‚ ligaments and tendons are all types of connective tissue that support your frame. The human skeleton is a wonder of design and engineering. It is incredibly strong and affords us great protection‚ but it is also incredibly light‚ giving us a great range of mobility. As you go on to explore the human body‚ knowledge of bone

An Animal Called Ant. Fachry Ardani People define ant as the smallest animal on earth. Although they are small‚ ants almost colonized almost every landmass on earth. Ants are very social insect‚ they form a group to build their own nest and search for foods while most of each nests consisted of one ant queen on every colony and thousands of ant workers. Most of the humans consider ant as a diligent and genius creatures‚ but apparently we have been looking at ant intelligence the wrong way

------------------------------------------------- HUMAN TOOTH------------------------------------------------- Teeth of humans are small‚ calcified‚ whitish structures found in the mouth that are used to break down food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums. Teeth are made of multiple tissues of varying density and hardness.COMPOSITION OF TOOTH | Four major tissues make up the tooth: * Enamel * Dentin * Cementum * Root Canal (Dental Pulp)The tooth is supported

minute. The skull is a bony structure in the head of most vertebrates (in particular‚ craniates) that supports the structures of the face and forms a protective cavity for the brain. The skull is composed of two parts: the cranium and the mandible. The skull forms the anterior most portion of the skeleton and is a product of encephalization‚ housing the brain‚ many sensory structures (eyes‚ ears‚ nasal cavity)‚ and the feeding system. Functions of the skull include protection of the brain

The numbers of molars in the coyote upper and lower jaws were the same as the number of molars in the human (upper + lower jaws). According to the dental formula data‚ not all skulls have the same numbers of different tooth types in the maxilla and mandible because each skull could have varied number of tooth types. The coyote (Canis latrans) had the largest skull and the human (Homo sapiens) had the smallest skull. The coyote and deer both had largest teeth while the human species had the smallest

A Review of Facial Nerve Anatomy Terence M. Myckatyn‚ M.D.1 and Susan E. Mackinnon‚ M.D.1 ABSTRACT An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy‚ parotidectomy‚ maxillofacial fracture reduction‚ and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits‚ and areas where these nerves are particularly susceptible to injury

craniomagnus in the other. I Based on the form and characteristics observed from the fossils found‚ we can describe the socio-ecology of the two different species. On the first site we discovered the species Bigapithecus ginormous. Based on the mandibles found on site‚ we identified that the teeth had high cusps and thin molar enamel. High cusps are meant for slicing and shearing along with the thing molar enamel creates very sharp edges on the teeth. We can conclude that this species were leaf eaters

Hyper & Hypopituitarism Introduction Hyperpituitarism is the result of excess secretion of adenohypophyseal trophic hormones. Hypopituitarism is the decreased secretion of one or more of the pituitary hormones. If there is decreased secretion of most pituitary hormones‚ this condition is called panhypopituitarism (pan meaning "all"). Historical Background The pituitary was known by Galen‚ and various theories were proposed about its role in the body. In the late 19th century‚ acromegaly
