Anatomists deal with the structure (morphology) of the body parts. This includes the shapes‚ forms‚ and placement of body organs and appendages. Physiologists deal with the functions of body parts‚ what the body parts do‚ and how this is accomplished. 3. How does a biological structure’s form determine its

Vertebral Compression Fracture (Thoracic) Overview- The spine is made up of bones called vertebrae. A vertebra can crack just like any other bone in the body. When the vertebral body collapses‚ this is called a vertebral compression fracture. These fractures occur more frequently in the thoracic spine (the central portion of the spine)‚ in particular in the lower part. These fractures are generally caused by a condition such as osteoporosis‚ a very hard fall‚ or another type of injury. Causes- The

IN HUMANS are two bean-shaped - about 4 inches long and about 2 ½ inches wide organs called kidneys which are located near the vertebral column at the small of the back . The main function of the kidneys are to purify the blood by separating urea‚ mineral salts‚ toxins and other waste products from it. Nature has so provided every human being a set of 2 kidneys so that blood purification runs on smoothly; one kidney assisting

Dissection Procedures: Brain‚ Trigeminal and Pterygopalatine Ganglia: After 48 hours‚ the brain was approached through the dorsal aspect of the skull. A T- shaped incision was given on the dorsal aspect of the head and the skin was reflected. The skull was nibbled avoiding damage to the brain. The brain was removed by releasing it gently from all its attachments from below and sides. Trigeminal ganglia were separated by cutting at the junction where the nerve enters into the brain stem. The brain

Exam 3 Hip and Thigh Anatomy of the Hip Hip and pelvic region are not synonymous * Hip is articulation of femur with pelvis * Pelvis consists of sacrum‚ coccyx‚ and 2 large hipbones on either side. * Hip bones are called innominates * have a right and left * pelvis and innominates protect reproductive organs * also part of birth canal * Serves as a stable platform * Supports the body weight * Links the sacrum with weight transmission

Different types of muscle contractions: Isometric- muscle contraction without a change in the length of muscle Concentric- Muscle applies force as it shortens (lifting) Eccentric- Muscle applies force as it lengthens (lowering) Difference between type 1 and type 2 muscle fibers * Slow-twitch fibers * Type-I fibers * Fatigue resistant * Contract slowly and with relatively little force * Rely primarily on oxidative energy system * Fast-twitch fibers
