SKELETAL SYSTEM The Arctic wolf’s body is built for long-distance travel and withstand different types of weather than other wolves. The Arctic wolf’s skeleton system is made for them to run‚ jump‚ and catch their prey. The part of the wolf’s skeletal starts with the part of the body that has bones of the limbs‚ skull‚ and a deep chest. 1. The limbs of the wolf include the legs and toes. The wolf has long legs‚ large paws‚ and short toes. The wolf has five toes on the forefeet and four toes on

In endochondral ossification bone tissue replaces hyaline cartilage‚ forming all bones below the skull except for the clavicles. (1) Osteoblasts secrete osteoid‚ creating a bone collar around the diaphysis of the hyaline cartilage model. (2) Cartilage in the center of the diaphysis calcifies and deteriorates‚ forming cavities. (3) The periosteal bud invades the internal cavities and spongy bone forms around the remaining fragments of hyaline cartilage. (4) The diaphysis elongates as

thickness by about 20 percent. The skin becomes thin and fragile and can no longer retain internal heat. For the Musculoskeletal‚ muscle mass is a primary source of metabolic heat. When muscles contract‚ heat will generate. The heat that the muscle puts out maintains body temperature‚ to require normal body function. Around the third decade of person’s life span‚ the muscle tissue reduces in size‚ elasticity and strength. As a result the body gets older and muscular activity becomes less takes more

The Physiology of Fitness Assignment 1 Helpsheet Step 1 You need to introduce your assignment‚ here I would define two key terms for the entire of this assignment these are chronic and acute. Example Answer There are many changes to the body during exercise; these can be classified as acute and chronic. Acute meaning they are short term and happen almost instantly with the onset of exercise. The other chronic is long term and allows the body to adapt its capabilities so therefore it

Before the motor neuron cone arrives the muscle fiber‚ AChR clusters are formed in the middle section of a muscle fiber. When the growing nerve cone attaches the muscle fiber‚ Agrin activates Lrp4‚ which then binds to the receptor tyrosine kinase MuSK‚ through this binding MuSK is phosphorylated and starts to form the neural and aneural AChR clustering (Burden 2011). Morphologic differences in the pre- and/or postsynaptic part of the NMJ can be a hint of a certain disease. In the following figure
