Anatomy review for the nervous system - Week 12 Study Guide 1. Distinguish the difference between neuron‚ neuroglial cells‚ Schwann cells‚ neurofibrils‚ and astrocytes. Neuron: masses of nerve cells in nervous tissue Neuroglial Cells: provide neurons physiological requirements (fill spaces‚ give support to neurons) Schwann Cells: larger axons of peripheral neurons enclosed in sheaths Neurofibrils: thin‚ long fibrils that run through body of neuron and extends to axon and dendrites; gives neuron

Evolution of Tasmanian Devils The world’s largest surviving carnivorous marsupial‚ the Tasmanian devil has a thick-set‚ squat build‚ with a relatively large‚ broad head and short‚ thick tail. The fur is wholly black‚ but white markings often occur on the rump and chest. Body size also varies greatly‚ depending on the diet and habitat. Adult males are usually larger than adult females. Devils once occurred on mainland Australia‚ but have been confined to Tasmania since pre-European times. The survival

“I personally think that this speech helped me mentally and physically. I become aware of the peace that this could bring the nation. It was written with an organised and systematic format. Martin was very direct aside from the complex figurative speech he used. Martin reinforced so much of the country’s history into his speech. All the strengths and weaknesses involved. His pattern and structure throughout the speech was developed and explained clearly. His repetition of the phrase ‘I have a dream’

Schwann (1868) - observed many kinds of animal tissue - concludes that all animals are made up of cells D. Schleiden (1869) - observed many kinds of plant tissue - concludes that all plants are made up of cells E. Cell Theory - came about from the work of Schleiden and Schwann Two major points: 1. All organisms are made up of one or more cells 2. Cells come from only pre-existing

NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

will cause loss of feeling in the skin and weakens muscle. B. Leprosy can affect the skin and Schwann cells of peripheral nerves. Which events of sensation processing are most likely not functioning properly in Sannu’s leprosy? Generation of nerve impulses is probably not working properly. Sensory neurons conduct impulses from the peripheral nervous system‚ so when the leprosy affects the Schwann cells of the peripheral nerves it is not conducting the impulse to integrate the sensory input.

which will be referred to as the auditory nerve for simplicity‚ consists of the cochlear and vestibular divisions. These two divisions‚ running from the inner ear to the brain‚ are responsible for transmitting information about hearing and maintaining balance‚ respectively. When the Schwann cells (used to keep peripheral nerve fibers alive) that surround the vestibular division grow at an abnormal rate inside if the ear canal‚ you’ve got yourself a case of acoustic neuroma. The resulting tumor from the uncontrolled growth of cells is benign

Like cement sets the foundation for a house‚ the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory‚ which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle‚ in 1839. Since the cell is the structural and functional unit of life as the house is for a community‚ without the house the community would be irritated and would not be stable‚ the community would therefore cease
