Nervous tissue

Question 1

Central nervous system components

Answer 1

Brain and spinal cord

Question 2

Peripheral nervous system component and function

Answer 2

Every nervous tissue beside CNS and acts as messenger between CNS and body

Question 3

Nervous tissue functions

Answer 3

1. Sensory of environment
2. Integrative - information analyses
3. Motor - Initiate action

Question 4

Neuron component and function

Answer 4

Contain 1. Dendrites convey action potentials and 2. Axons convey impulses to other neurons

Question 5

Multipolar neuron

Answer 5

Motor neuron to control muscle cell - many dendrites

Question 6

Bi polar neuron

Answer 6

Sensory neuron that relays information between receptor to neuron - Many branches, one axon and dendrite

Question 7

Uni polar neuron

Answer 7

Sensory nerve response - Continous convergence of axon and dendrites and branches and cell body outside the line

Question 8

Anaxonic neuron

Answer 8

Brain neuron - Many dendrites and branches

Question 9

Neuroglia function

Answer 9

Structure and repair nervous tissue, phagocyte, nutrients supply, regulate interstitial fluid

Question 10

Astrocyte -

Answer 10

CNS neuroglia

Supports, repairs, communciates with neurons, maintain homeostais of neuron and blood brain barrier

Question 11

Oligodendrocyte

Answer 11

CNS Neuroglia

Insulation of neuron and accelerates action potential

Question 12

Microglia

Answer 12

CNS neuroglia

Phagocyte/macrophage

Question 13

Ependymal cell

Answer 13

CNS Neuroglia

Lines cavities where cerebrospinal fluid flows to assist movement via cilia

Has microvilli to sense, sample and modify CSF

Question 14

Shwann cell

Answer 14

PNS neuroglia (Like oligodendrocyte)

Insulating myelin sheath around axon for structural support

Question 15

satellite cell

Answer 15

PNS neuroglia (Like astrocyte)

Maintains environment of peripheral neurons and provides support and fluid exchange
