Pharynx SG
Pharynx and Nasal Cavity
| Question | Answer |
|---|---|
| Buccinator Muscle Attachments | Posterior: Pterygomandibular raphe. Anterior: Inserts into cheek |
| Superior pharyngeal constrictor | Skeletal muscle that squeezes and compresses the back of the throat to assist in swallowing |
| Pterygomandibular raphe attachments | Has an attachment to the pterygoid hammulus and lower attachment at the medial side of the mandible |
| Pharyngeal constrictors | Superior, middle and inferior. They push into the cavity in front of them. They make a raphe (seam) that runs up and attaches to the base of the skull called the pharyngeal tubercle |
| Cricopharyngeal muscle | Makes a complete ring, acts as a sphincter and always contracted so you don't consistently swallow air. Relaxes when you swallow |
| What is continuous with the cricopharyngeus muscle? | Esophagus |
| Actions of stylohyoid muscle and stylopharyngeus muscle | Stylohyoid: Elevates hyoid. Stylopharyngeus: Elevates pharyngeal apparatus when it contracts |
| Soft Palate Functions | Raises up and closes airway when you are vocalizing. Baby uses soft palate to suck. Closes off nose when drinking |
| What elevates the soft palate? | Levator veli palatine |
| Areas behind the pharynx | Laryngopharynx: Area behind the larynx. Oropharynx: Area behind the mouth. Nasopharynx: Area above the soft palate and behind the nasal cavity |
| Pharyngeal Wall layers: outside to inside | Mucous membrane, Pharygobasilar fascia, pharyngeal constrictors, buccopharyngeal fascia |
| Pulsion diverticula | If pressure builds up it can blow out the sides of the pharynx |
| What lies posterior and inferior to the pharynx | The thyroid and parathyroid glands, recurrent laryngeal nerves and carotid arteries |
| What makes the aponeurosis of the tensor soft palate? | Tensor veli palatini |
| Pterygoid hammulus | Little hook that comes off the medial plate |
| What innervates the tensor veli palatini muscle? | Trigeminal nerve |
| Pharynotympanic tube | Projects itself into the posterior aspect of nasal cavity. Job is to equilibriate the changes of pressure in the chamber. Lined with mucosa. Goes from pharyngeal area to middle ear. |
| Drainage of Sphenoid sinus | Anteriorly below the sphenoethmoidal recess |
| Superior, middle and inferior conchae | Superior and middle nasal conchae are part of ethmoid bone. Inferior is its own bone |
| Innervation from Trigeminal | Sensory fibers from ophthalmic nerve. Maxillary sends sensory fibers: Greater palatine: Hard palate, Lesser palatine and least palatine |
| Greater petrosal | Synapses in the pterygopalatine ganglion |
| Parasympathetic and Sympathetic | Parasympathetic innervates glands. Sympathetic innervates blood vessels (Superior cervical ganglion) |
| Blood supply | Sphenopalatine artery (terminal branch of maxillary artery) is a major artery for the mucosa on the inside of the nose |
