Final Flashcards
Swallowing is initiated voluntarily in the oral cavity. This is followed by involuntary control. This involuntary control is regulated by…
Bilateral cortical interhemispheric and brainstem connections
Failure to close this sphincter during swallowing results in leakage of teh bolus or air into the nasopharynx and diminished ability to generate appropriate oropharyngeal pressures to propel the bolus through the oropharynx.
Velopharyngeal sphincter
The tongue is made up of intrinsic muscles and extrinsic muscles. Together these muscles help the tongue to manipulate and collect the bolus. Which lingual muscles lower the tongue, protract it anteriorly, and elevate the tongue?
Extrinsic muscles: genioglossus, hyoglossus, styloglossus, palatoglossus muscles.
At rest this sphincter is in a state of tonic contraction that minimizes the entrance of air into the gastrointestinal tract during respiration. The major component of this sphincter is the cricopharyngeal muscle. Relaxation of this sphincter begins after the onset of swallowing and lasts 0.5 to 1 second.
Upper esophageal sphincter
These pharyngeal structures are involved in deglutition and form the posterior and lateral pharyngeal walls.
The superior, medial, and inferior pharyngeal constrictors.
Swallowing can be visualized as the passage of the bolus through a series of dynamic chambers. These chambers are separated by sphincters (gates) that help to prevent spillage of the material before it enters the next chamber.
True
Normal bolus movement through the oral and pharyngeal cavities is a combination of opening/closing of sphincters, pressure and tongue posture
True
Which muscle is NOT involved in elevation of the hyoid/laryngeal complex?
Omohyoid
The primary sensory (afferent) control of the tongue, lips, and mandible is via cranial nerve…
CN V Trigeminal
Sensory and motor integration of the phases of swallowing suggests that…
Voluntary and involuntary aspects of swallowing may occur in parallel.
If the hyoid elevates and moves forward, the larynx will move ______ and _____ unless it is stabilized or restricted by other muscles.
upward,forward
The suprahyoid muscles are responsible for elevating the hyoid bone. Which of the following are suprahyoids?
Mylohyoid, Stylohyoid, and Digastrics
The teeth are the primary manipulators of the bolus during the oral phase of swallowing.
false
The tongue is made up of intrinsic muscles and extrinsic muscles. Together these muscles help the tongue to manipulate and collect the bolus. Which lingual muscles shape the tongue for management of various types of food and liquid? They also form a pocket to hold the bolus in place and keep it from falling into the cheek or spilling into the oropharynx.
Intrinsic muscles: transverse, vertical and longitudinal fibers
There are four common patterns of respiration coordination in swallowing. Choose the most common (and also the most protective) pattern found in healthy adults during drinking.
EX/EX (expiration, apnea event, expiration)
A clinical swallow screening can be performed and documented by a nurse, speech-language pathologist, or occupational therapist.
True
Respiration has no influence on swallowing function and therefore need not be considered during patient examination.
false
Which of the following is a part of the case history?
Gathering information on a family history of swallowing disorders, Gathering information on medications and their dosages, Gathering information on any recent weight changes, and Exploring reported evidence of trauma in the patient’s medical history and considering how a history of trauma may impact your relationship with the patient
The clinical swallow evaluation…
Should be relied upon to detect silent aspiration.
The presence of facial asymmetry can contribute to oral preparatory and/or oral phase dysphagia.
true
Oral Phase: Lip Seal
Assess by eliciting a cheek puff from the client.
Oral Phase: Tongue range of motion
Assess by eliciting the following movements: “Lateralize, elevate, and depress tip of tongue.”
Oral Phase: Tongue strength
Assess by pressing the tongue against resistance (such as against a tongue depressor or gloved hand).
oral phase: tongue sensation
Assess by lightly touching different parts of the tongue and oral cavity. Clinicans can also use flavored swabs on different parts of the tongue to assess taste.
oropharynx: soft palate motion
Assess by asking the client to open the mouth. Observe movement during /a/ and “ah-ah-ah” phonation.
oropharynx: soft palate sensation
Assess by touching the structure with a tongue blade or cotton swab. Ask the client if they felt the touch and where they felt it.
