0
Q
Skeletal muscle
A
Found in muscoskeltal system Movement. Bone to tendon. Myocytes or muscle fibres Neuron cell body Cytoplasm of the muscle
1
Q
Muscle
A
Capable
Spontaneously
Response to external stimuli
2
Q
Sm
A
Fibre are myofibills Repeated as sacromeres Composed as mircofilamentsz Proteins actin and myosin Overlap Mechanisms impluses arrivint the neuromuscular
3
Q
Cardiac muscle
A
Found in heart. Branched cells
Inteecalated disc
Demosomal like cell adhesions and gap junctions
Free movement of ions
4
Q
Cardiac
A
Electrical syncyhm Depolarisation and contraction of all connected cells Canadian contains myofibills Striated appearance Ca ions which bind troponin Cells able to depolarise
5
Q
Smooth muscle
A
Walls of internal organs In gt Slow movements Cells of smooth muscle Spindle shaped
6
Q
Smooth
A
Electrical continuity
Gap junctions
Z line
Shorter and fatter
7
Q
Nerve
A
Neuroma and glia Excitable Support cells Axons of neutrons Regulate the ionic
8
Q
Neurons
A
Has nucleus Dendrites and an axon Electrical activity Constructed Complex Have 10.000 information cells Synapses Axon of 1 neuron and dendrites
9
Q
Action potential
A
Transmits waves along axon
Phenomenon
Recorded along axon
Electrode in axon
10
Q
Myelination
A
Slow process
Opening na channels
Conduction enhanced because axons surround myelial
Specialised glial cell
Brain these cells are known as oligodendrolia
11
Q
Synaptic transmission
A
Single axon Termination Dendrite a synapse Small swelling at axon Axon triggers opening
