Chordates Reginald Bushner February 15‚ 2013 1 Abstract The word chordate originates from the word chorda or cord. Chordates are a very large group of animals with backbones. These animals have backbones or spines and inside are spinal cords‚ and an internal skeleton as part of their nervous system. It is believed that chordates have originated from invertebrates. It is difficult to determine from which invertebrate group the chordates were developed. Chordate ancestors were soft

Skeleton The axial skeleton forms the main axis or core of the skeletal system. It consists of the skull‚ vertebral column‚ and thoracic cage. As noted by Adams et al. (2010)‚ the axial skeleton consists of 80 bones. The axial skeleton has two functions. The first is that it provides support and protection for the organs in the dorsal and ventral cavities such as the brain‚ and the spinal cord. It

hypothalamus’s main function is that of homeostasis. In order for the hypothalamus to successfully fulfill this task‚ it must receive inputs about the body’s "state‚" and it must be able to create changes in the body that will correct anything that might be misaligned. The hypothalamus receives inputs from the nucleus of the solitary tract‚ which provides it with information about gut distension and blood pressure. The reticular formation tell the hypothalamus about the body’s skin temperature. Inputs received

additional contributions to the definition of Chiari II malformation. The first known malformation was a 17-year-old female in 1883. CM is a congenital anomaly in which parts of the brain protrude through the opening in the base of the skull into the spinal column. Chiari used to be considered a rare disorder‚ although‚ due to advances in modern technology‚ it is said that there is more people diagnosis. One in one thousand children‚ approximately‚ are born with this disorder every year.
