Nervous Tissues Flashcards
1
Q
Types
A
Neurons, Neuroglia
2
Q
Components
A
Brain, spinal cord, nerves
3
Q
Neurons
A
Structural and functional cells
Transmit & receive nerve impulses
4
Q
Neuroglia
A
Supporting
Highly branched
Don’t conduct nerve impulses
5
Q
Function
A
Transmits electrical signals from sensory receptors to
effectors (muscles and glands)
6
Q
Sensory neuron
A
Receives transmission, transports signal to spinal cord
Cell body is stored attached to the axon, not dendrites => faster transmission
7
Q
Motor neurons
A
Large central nucleus, dendrites, a long thin axon.
Returns signal to muscles/glands
8
Q
Interneuron
A
Found in the spinal cord, transfers signals from sensory -> motor
Shorter and no myelin sheath
