Study Notes
Laryngeal Cartilage and Aspiration
- The laryngeal cartilage preventing aspiration of foreign bodies is the epiglottis.
- It acts as a flap during swallowing, covering the entrance to the trachea.
Hyoid Bone Structure
- The hyoid bone is uniquely positioned, attached to the upper part of the thyroid cartilage via ligaments and is also connected to the mucous membrane.
- It is not directly connected to other bones, allowing for a range of motion in swallowing and speech.
Soft Palate Structure
- The structure extending from the posterior nasal spine to the superior portion of the soft palate is the palatine aponeurosis.
- This structure provides support and contributes to the function of the soft palate.
Autonomic Nervous System Divisions
- The autonomic nervous system is divided into two main parts: Sympathetic Nervous System (SNS) and Parasympathetic Nervous System (PNS).
Neurotransmitters
- The primary neurotransmitter for the Sympathetic Nervous System is norepinephrine.
- The primary neurotransmitter for the Parasympathetic Nervous System is acetylcholine.
Respiratory Effects
- The Sympathetic Nervous System naturally causes bronchodilation, allowing for increased airflow to the lungs.
- The Parasympathetic Nervous System naturally causes bronchoconstriction, reducing airflow and promoting rest.
System Functions
- The Parasympathetic Nervous System is often referred to as the "rest and digest" system, promoting relaxation and digestion.
- The Sympathetic Nervous System is commonly known as the "fight or flight" system, preparing the body for rapid response in stressful situations.
Laryngeal Cartilage
- The epiglottis is the laryngeal cartilage that prevents aspiration of foreign bodies into the airway.
Hyoid Bone and Thyroid Cartilage
- The hyoid bone is attached to the upper portion of the thyroid cartilage, which is an unpaired cartilage of the larynx.
Soft Palate Structure
- The structure extending from the posterior nasal spine to the superior portion of the soft palate is known as the palatine aponeurosis.
Autonomic Nervous System Divisions
- The two divisions of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system.
Neurotransmitters
- Norepinephrine (noradrenaline) is the primary neurotransmitter for the sympathetic nervous system.
- Acetylcholine is the neurotransmitter for the parasympathetic nervous system.
Bronchodilation and Bronchoconstriction
- The sympathetic nervous system naturally bronchodilates, allowing for increased airflow in the lungs.
- The parasympathetic nervous system naturally bronchoconstricts, reducing airflow into the lungs.
Autonomic System Functions
- The parasympathetic nervous system is referred to as "rest and digest," promoting relaxation and restorative processes.
- The sympathetic nervous system is known as "fight or flight," preparing the body for stressful situations.
Laryngeal Cartilage
- The epiglottis is the laryngeal cartilage responsible for preventing aspiration of foreign bodies into the trachea during swallowing.
Hyoid Bone and Thyroid Cartilage
- The hyoid bone is positioned superiorly to the thyroid cartilage, serving as an anchor point for several muscles involved in swallowing and speech.
Nasal Structure
- The structure extending from the posterior nasal membrane is known as the nasopharynx, which connects the nasal cavity to the pharynx.
Autonomic Nervous System Divisions
- The autonomic nervous system is divided into two main branches: the sympathetic nervous system and the parasympathetic nervous system.
Neurotransmitters
- The neurotransmitter associated with the sympathetic nervous system is norepinephrine, while acetylcholine is the neurotransmitter for the parasympathetic nervous system.
Bronchodilation
- The sympathetic nervous system facilitates natural bronchodilation, which helps expand air passages in the lungs.
Bronchoconstriction
- The parasympathetic nervous system leads to natural bronchoconstriction, narrowing the airways and reducing airflow.
"Rest and Digest" System
- The parasympathetic nervous system is often referred to as the "rest and digest" system, promoting relaxation and digestion.
"Fight or Flight" System
- The sympathetic nervous system is known as the "fight or flight" system, preparing the body to respond to stressful situations by enhancing alertness and physical readiness.
