A & P of Speech

Elementary Tissue Types 3 and 4

QuestionAnswer
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
