ANPH 1001 The Final Exam With Complete Solution
afferent or sensory - ANSWER Convey info from the receptors in the central nervous
system
Efferent peripheral system - ANSWER Convey info from the central nervous system to
muscle and glands
What is the Efferent system divided into? - ANSWER Somatic nervous system and the
autonomic nervous system
Somatic Nervous System - ANSWER Conducts impulse from the brain and the spinal
cord(CNS) to skeletal muscles- enable us to respond to outside environment
autonomic nervous system - ANSWER Involuntary- conducts impulse from the brain and
the spinal cord to smooth muscles (e.g. intestines) cardiac muscle, glands
What are the 2 divisions of the autonomic nervous system? - ANSWER 1. Sympathetic
2. parasympathetic
nerve tissue - ANSWER Consists of grouping of nerve cells called neurons
- Neurons transmit nerve impulse in form of electrochemical changes
Nerve - ANSWER A bundle of nerve cells or fibers
Neuroglia (nerve glue) - ANSWER support and protect neurons; 60% of all brain cells are
neuroglia cells (do not conduct impulse)
, Different types of neuroglia cells - ANSWER 1. Astrocytes
2. Oligodendroglia
3. Microglia
4. Microglia
5. Ependymal
6. Schwann
Astrocytes - ANSWER Star shaped that wrap around nerve cells
Oligodendroglia - ANSWER Look like small osteocytes- Support forming semi rigid
connective tissue, myelin sheath, formations on neurones of brain and Spinal cord
Microglia - ANSWER Small cells whose role is to engulf and destroy microbes and
cellular debris- phagocytes
Ependymal - ANSWER Line the fluid filled ventricles of the brain, Some produce
cerebrospinal fluid, some with cilia to move fluid
Schwann - ANSWER Myelin sheaths in peripheral nervous system
What are the 2 kind of nerve fibres on the nerve cell - ANSWER 1. Dendrite
2. Axon
Dendrite - ANSWER Short branched receptive areas of neutron
Axon - ANSWER Long finer, peripheral axons enclosed in Melin sheaths produced by
Schwann cells
Structural Classification of Neurons - ANSWER 1. Multipolar
