What are cadiac, skeletal, and smooth?
100
The neurotransmitter released from a neuron to act on a muscle cell.
What is Acetylcholine?
100
Made of many motor neurons bundled together.
What is a motor neuron?
100
This type of bone makes of the rigid outer layer of bone, is densely packed with a calcified matrix and supplied directly by blood vessels.
What is compact bone?
200
This is a type of synapse where 2 neurons are directly connected and an electrical charge passes from one neuron to the next.
What is an electrical synapse?
200
The 4 functional characteristics of muscle tissue.
What are excitability, extensibility, elasticity, contractability?
200
The area where a muscle cell generates and propagates an AP.
What is the sarcolemma (cell plasma membrane)?
200
The response of muscle fibers to a single AP from their motor neuron.
What is a muscle twitch?
200
This type of bone is made of lattice-like trabeculae lined with osteogenic cells that receive nutrient supply via diffusion.
What is cancellous bone?
300
This is a type of synapse where there is a physical gap between the 2 neurons and communication is achieved through a neurotransmitter.
What is a chemical synapse?
300
The 5 functions of muscle tissue.
What are producing movement, maintaining posture/body position, stabilizing joints, generating heat, and protection/sphincters/pupils/"goosebumps"?
300
The term used for an action potential pairing with a muscle contraction?
What is excitation-contraction coupling?
300
A charting system with traces the electrical activity of a muscle contraction?
What is a myogram?
300
The 6 functions of bone.
What are support, protection, movement, mineral/growth factor storage, blood cell formation and triglyceride storage?
400
These neurotransmitters unlock/open gated ion channels on the postsynaptic membrane which will cause a depolarizing graded potential (increased chance of generating an AP).
What are excitatory neurotransmitters?
400
These thick filaments consist of many molecules whose heads protrude at opposite ends of the filaments.
What are myosin filaments?
400
The action potentials generated on the sarcolemma moves down the ______________.
What are the t-tubules?
400
The 3 periods of muscle twitch.
What are the latent, contraction and relaxation period?
400
The outer fibrous double bone membrane layer is the ___________, whereas the inner layer that lines the internal bone surfaces is the ___________.
What is the periosteum and the endosteum?
500
These neurotransmitters unlock/open gated ion channels on postsynaptic membrane which will cause a hyperpolarizing graded potential (decreased chance of generating an AP).
What are inhibitory neurtransmitters?
500
These thin filaments consist of 2 strands of sub-units twisted into a helix plus 2 types of regulatory proteins?
What are actin filaments?
500
The movement of the AP down the t-tubules triggers the release of ________ ions from the _________________.
What is calcium and sarcoplasmic reticulum?
500
The 4 factors affecting the force of muscle contraction.
What are the number of muscle fibers stimulated, size of muscle fibers, frequency of stimulation, and degree of muscle stretch?
