Flashcards in Lecture 31: REVIEW! Deck (18):
1

Afferent =

- IN flow

2

Efferent =

- OUT flow

3

Cells of the nervous system:

- Glia
- Neurons

4

Basic properties of Neurons:

- Input, Conduction, Output Zone
- Synapse
- Electrical ---> Chemical ---> Electrical
- Axon Hillock

5

Glia (CNS) include:

- Astrocytes
- Microglia
- Ependymal Cells
- Oligodendrocytes

6

Glia (PNS) include:

- Schwann Cells

7

Spinal Cord also has:

- Grey Matter
- White Matter

8

Cranium includes:

- Skull
- Meninges
- Facial skeleton

9

The brain is actually hollow so also has a...

- Ventricular system

10

Three different types of white matter:

- Corticospinal Tract
- Etc.

11

The structure of the skeletal muscle:

- The motor unit, neuromuscular junction

12

The motor unit:

- A motor neuron and all the muscle fibres it innervates

13

Neuromuscular Junction occurs using what kind of coupling?

- Electro - Chemical - Electro

14

Mechanisms of Contraction of Skeletal Muscle

- Excitation
- Contraction
- Relaxation

15

Energy Sources for Contraction:

- Creatine-Phosphate
- Anaerobic vs. aerobic

16

Skeletal muscle fibre types:

- Slow/Red
- Fast/White
- Exercise & Fatigue

17

Skeletal, Cardiac and Smooth muscle:

- Structural & functional differences; why do we need them?

18

Pre motor cortex and planning and role of basal ganglia. Circuitry that allows this to happen. Role of interneurons in spinal reflexes. Voluntary skeletal muscle control system. Reflex arcs. Can engage autonomic system.
