Muscular System 2
Diagrams
100
This part of the neuron receives chemical messages from the neurotransmitters of other neurons.
What are dendrites?
100
These are the 2 types of nervous cells.
What are neurons and neuroglial cells?
100
These are the three types of muscle tissue.
What are Skeletal, Smooth, Cardiac?
100
This type of muscle is found in the heart.
What is cardiac?
100
This part of the nervous system is labeled in yellow.
What is the central nervous system?
200
This division of the autonomic nervous system initiates the "fight or flight response".
What is the sympathetic nervous system?
200
This is the long extension that transmits signals away from the cell body of a neuron.
What is the axon?
200
These types of muscles are voluntary.
What are Skeletal?
200
This is when a muscle shortens in order to move the body.
What is a Contraction?
200
The lobe colored green.
What is the occipital lobe?
300
This structure helps pass information between the two hemispheres of the brain.
What is the corpus callosum?
300
A series of events cause the electrical charge inside the cell to move from its negative resting state (-) to its positive depolarizer state (+) and back to its negative resting state (-).
What is the action potential?
300
Thin filaments in a myofibril are called this.
What is actin?
300
A muscle fiber cannot contract until ___________ rushes in from a nerve cell to remove the blocking molecules (tropomyosin) and make the active site available to be engaged.
What is calcium?
300
The structure colored red.
What is the cerebellum?
400
This lobe is responsible for making decisions, plans, reasons, and carries out behaviors.
What is the frontal lobe?
400
The Brain Stem controls these functions.
What is autonomic functions like posture, breathing, and heart rate?
400
The act of the myosin pulling the actin in a muscle contraction is called this.
What is a power stroke?
400
These structures are bundles found within the muscle.
What are fascicles?
400
This structure is labeled 2. It is the connective tissue that surrounds the whole muscle.
What is the Epimysium.
500
The cerebellum has this main function.
What is coordinates movements and mantains balance?
500
What is the left side of the cerebrum know for?
Logic and math
500
During rigor mortis, __________ floods the muscle fibers but a lack of ____________ prevents them from detaching.
What is Calcium; ATP?
500
This model explains muscle contraction as the process where thin actin filaments slide past thick myosin filaments, causing the muscle's contractile unit (sarcomere) to shorten without the filaments themselves changing length.
What is the sliding filament model?
500
This structure is numbered 7.
What is the myofibril?
