Power Proteins
Tightly coiled, these proteins anchor the ends of the thick filament to the Z Line.
What is titin?
The neuron & muscle fiber meet and communicate signals together through this specific area?
What is the neuromuscular junction?
Units of these spring-loaded structures stack atop one other to make up a single myofibril.
What is a Sarcomere?
Thin filament is made of these beads of protein that possess an active site for thick filament proteins to latch onto.
What are G-Actins?
Stored in the synaptic bulb of a neuron, these chemical neurotransmitters get released into the synaptic cleft to specific receptors located along the motor end plate.
Filaments ->Sarcomere->Myofibril->Muscle Fiber-> Fasicle-> Skeletal Muscle Tissue
This protein makes up the zig-zag endings of a sarcomere's Z-Line.
What is actinin?
In order, what are the two types of signal releases that take place starting from:
1. The Axon.
2. The Synaptic Cleft
3. The Sarcolemma
4. The Terminal Cisternae
1. Electrical
2. Chemical
3. Electrical
4. Chemical
Making up the length of the thick filament, these golf-club shaped proteins work together to pull the thin filament in during the contraction cycle.
What is Myosin?
This protein acts as a locking mechanism, requiring an ion from the terminal cisterna to bind to it as part of exposing the G-Actin active sites.
What is troponin?
This enzyme is released to clear away the Ach neurotransmitter and reset the contraction cycle.
What is Acetyolcholinesterase?
This raw source of molecular energy is given to myosin to detach it from the active site of a G-Actin bead.
What is ATP?
This protein wraps around the F-Actin strand of thin filaments, covering the active sites away from the thick filament proteins.
What is tropomyosin?
These bell-shaped ends of the sarcoplasmic reticulum store calcium ions and make up part of a triad group with its partner, the T-Tubule.
What is the terminal cisternae?
This infolding structure that makes up part of the triad helps carry a stimulus for contraction deep into the myofibrils.
What is the T-Tuble?
