Components Of The Control And Communication Network - Lecture 10 Flashcards
1
Q
Central Nervous System
A
- Brain
- Spinal Chord
2
Q
The Peripheral Nervous System
A
- Somatic Nervous System
- Autonomic Nervous System
3
Q
The Endocrine Sytem
A
- Endocrine System
- Exocrine System with Endrocrine-like Activity
4
Q
The Local Support and Defence System
A
- Maintenance and Support System
- Adaptation and Repair System
- Resident Defence System
- Migrant Defense System
5
Q
5 Major Cell Types
A
- Neurons
- Oligodendrocytes (CNS) and Schwann cells (PNS)
- Astrocytes
- Microglia
- Ependymal Cells
6
Q
Neurons
A
- Information Flow
- Built for speed
- built to signal specific target cells with a specific neurotransmitter
- build to be excitatory or inhibitory
- build o diverge, converge and form networks
7
Q
Multiple Sclerosis
A
Destruction of myelin sheath, due to an autoimmune disorder
8
Q
Oliogendrocytes and Schwann Cells
A
- Produce myelin
- span multiple axons in CNS not PNS
9
Q
Astrocytes
A
Stellate morphology, important for communication and more abundant than neurons
10
Q
Microglia
A
Mobile macrophage-like immune cells
11
Q
Ependymal Cells
A
Line ventricles to form a barrier; produces cerebrospinal fluid
12
Q
5 key functions of Astrocytes
A
- provide nutrients to neurons
- function of the Ependymal cells
- function are the nodes of Ranvier
- Participate in/form tripartite synapses with neurons
- super hubs for neural networks via syncytium formation and calcium signalling
