A & P of Speech
Elementary Tissue Types 3 and 4
| 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 |
