Neuron |
Easily simulated and transmit nerve impulses bound together by connective tissue
|
|
|
Neuronal sheaths? |
Dense connective tissue epineurium surrounds the neuron. Perineurium surround bundles of nerve fibres. Endoneurium surrounds individual neuron |
|
|
Types of neurons? |
Sensory (afferent) - carries impulses from sensory organs to CNS. Motor (efferent) - from CNS to effector organs. Interneurons (connectors) - connect both the types of neurons. |
|
|
Structure of a neuron? |
Dendrites and axons |
|
|
Granules found in the cytoplasm of a neuron |
Nissl's bodies |
|
|
Axon is surrounded by_______ |
A whitish fatty later - myelin sheath. Myelin is surrounded by neurilemma or layer of Schwaan cells. Together they are called Medullary sheath. |
|
|
Medullary sheath is interrupted by? |
Nodes of Ranvier |
|
|
Classification of neurons? |
Unipolar - single process or fibre. Multipolar - numerous cell processes (one axon and many dendrites) Bipolar - dendrite at one end and neuron at the other end. |
