Question | Answer |
This tissue is the mediation of movement. It's unit are elongated cells with contractile properties | Muscular |
Three basic types of muscle tissue | Striated, Smooth, and Cardiac |
This muscle tissue moves parts of the skeleton and is voluntary which is controlled by the CNS, has long fibers with striations and examples include the muscles for speech production. | Striated |
Architecture of muscle | Morphologies |
3 Morphologies of Striated muscle | parallel, radiating, pennate |
The morphology that can contract up to half of their size and known for their movement. | Parallel |
The morphology that radiates out, has less movement but more strength and is known for its power | Radiating |
The morphology that combines for the ability to contract, is strong and fast, and is known for its power and movement | Pennate |
This muscle tissue does not connect at a point and is found in the glandular, intestines, and vascular system. These fibers are spindle shaped, they dont cross, involuntary, contracts slowly, and is controlled by the ANS. | Smooth |
This muscle tissue is striated but somewhat scattered and involuntary. | Cardiac |
Something that surrounds muscle like a fascia | Perimysium |
This provides the influx to move to muscles | Nerve supply |
___ is determined by the diameter as well as morphology of a muscle | Strength |
___ can be up to 50% of the length of a muscle with parallel fibers | Contraction |
___ of muscles work the opposite way | Antagonists |
____ is when the muscle tension is more than the resistance causing movement. When the muscle shortens | Isotonic contraction |
Is when the tension is less than resistance causing no movement. The muscle lengthens. | Isometric contraction |
A functional unit for muscle action. The motor neuron, axon, and muscle fibers innervated. A section of muscle that is contracted by one motor neuron and the fibers its serving. The efferent nerve fiber. | Motor unit |
The functional unit for muscle action that is the nerve cell. | Motor neuron |
The electro-physiological activity of a motor neuron, and can be monitored with an EMG. Is a functional unit for muscle action. | Muscle action potential |
This specialized tissue with a predominance of cells that communicate through impulses. Moves our speech muscles. | Nervous tisue |
The unit of nervous tissue | Neuron |
Three different direction of impulses... | afferent, efferent, and association/processing |
The impulse that is towards the body and sensory/input | afferent |
The impulse that is motor/excitatory | efferent |
The impulse that is of sensory and motor info as well as cognition, attention, attitude, and memory. | association/processing |
Connection of nervous tissue: neuron to___ | neuron |
Connection of nervous tissue: neuron to ___ | sensory receptor cell |
Connection of nervous tissue: neuron to___ | muscle fibers |
Prime movers are helped by ___ which are muscles that stabilize structures. | Synergists |
