PPT-The Brain & Cranial Nerves

Sarah Cronin Matt hawkins Tyler plas Marissa kramer The adult human brain contains about 98 of the bodys neural tissue A typical brain weighs about 14kg The brain of a male is usually about 10 . This tutorial will allow you to learn about the 12 pairs of cranial nerves in the human body.. An introduction to the cranial nerves is followed by a screen which allows you to click on the nerve name to learn the functions and tests for the assessment for each nerve.. Cranial. Nerve.

Vertebral column. Thoracic cage. Appendicular skeleton. Pectoral and pelvic girdles. Upper and lower limbs. Skeletal system includes both:. 2. The Skull. 3. The cranium. Cranial vault or calvaria. 1. The Nervous System can be divided in: . Central Nervous System (CNS). Brain and Spinal Cord. Peripheral Nervous System (PNS). Cranial and spinal nerves, ganglia, sensory receptors. 2. Division of the Peripheral Nervous System. 31 pairs arise from spinal cord. Five groups correspond to regions of spinal cord and vertebrae. Cervical 8 pr.. Thoracic 12 pr.. Lumbar 5 pr..

Fibers leave the pons, travel through the internal acoustic meatus, and emerge through the . stylomastoid. foramen to the lateral aspect of the face. Motor functions include facial expression, and the transmittal of autonomic impulses to lacrimal and salivary glands. How-I-do-itBernd F. Tomandl; Norbert Sommer; Patrick J. Egan; Tibor C.
