Senuweeweefsel/ Nervous tissue Notes

Senuweeweefsel/ Nervous tissue

• Bestaan uit gespesialiseerde selle = neurons / Consist of specialised cells = neurons
• Vorm die sentrale Senuweestelsel en perifere Senuweestelsel / Forms the central nervous system as well as peripheral nervous system

Sensoriese neuron / Sensory neuron

• Diagram of a sensory neuron is shown, labeling the following:
  • Selliggaam / Cell body
  • Kern / Nucleus
  • Mielienskede / Myelin sheath
  • Monopolêr / Monopolar

Interneuron

• Interneuron = Multipolêr/Multipolar

Motoriese neuron / Motor neuron

• Multipolêr / Multipolar
• Dendriet neem impuls NA die selliggaam / Dendrite Takes impulse TO cell body
• Akson = Neem impuls WEG van selliggaal / Axon Takes impulse AWAY from cell body
• Rigting van impuls/Direction of impulse
• Senuweeseefsel laat 'n organisme toe om stimulus te ontvang en daarop te kan reageer / Nerve tissue allows an organism to receive a stimuli and to react on it

Motoriese neuron / Motor neuron

• Diagram of a motor neuron, labeling the following:
  • Dendriete / Dendrite
  • Akson / Axon
  • Kern/Nucleus
  • Mielienskede / Myelin sheath
  • Schwansel / Shwan cell
  • Nissl korrels / Nissl granules
  • Kern van Schwansel / Nucleus of Schwann cell
  • Ranvierknoop / Node of ranvier
  • Selliggaam / Cell body
  • Rigting van impuls/Direction of impulse
