The human upper respiratory, or aerodigestive, tract serves as the crossroads of our breathing, swallowing and vocalizing pathways. Accordingly, developmental or evolutionary change in any of these functions will, of necessity, affect the others. Our studies have shown that the position in the neck of the mammalian larynx is a major factor in determining function in this region. Most mammals, such as our closest relatives the nonhuman primates, exhibit a larynx positioned high in the neck. This… 

Chapter 2 Evolution and Development of Human Swallowing

  • Medicine, Biology
  • 2019
This chapter will describe the human swallowing in comparison with other mammals. Besides, the context will focus on swallowing and feeding development in infants. The basic knowledge of how

Developmental changes in the shape of the supralaryngeal vocal tract in chimpanzees.

TLDR
The hypothesis that the descent of the larynx evolved in at least two steps during hominoid evolution is supported.

Voice and Dysphagia

TLDR
The chapter reviews the main changes in the physiological and physiopathological characteristics of the upper respiratory and digestive tracts and the impact that artistic vocal performances have on swallowing and a review of the literature on the topic.

Embryology and evolutionary history of the respiratory tract

TLDR
Combining key features of human lung embryology with comparative respiratory anatomy reinforces the relationship between structure and function, and will facilitate a deeper comprehension of lung development.

Development of the supralaryngeal vocal tract in Japanese macaques: implications for the evolution of the descent of the larynx.

TLDR
The evolutionary path of the great descent of the larynx is likely to be explained by a model comprising multiple and mosaic evolutionary pathways, wherein these developmental phenomena may have contributed secondarily to the faculty of speech in the human lineage.

The Avian Lingual and Laryngeal Apparatus Within the Context of the Head and Jaw Apparatus, with Comparisons to the Mammalian Condition: Functional Morphology and Biomechanics of Evaporative Cooling, Feeding, Drinking, and Vocalization

TLDR
This chapter will concentrate on the functional-morphological interdependences and interactions of the lingual and laryngeal apparatus with each other and with the skull and jaw apparatus.

Comparative Morphology and Physiology of the Vocal Production Apparatus and the Brain in the Extant Primates.

Anatomy of reflux: a growing health problem affecting structures of the head and neck.

TLDR
While it has become apparent that GER must precede both GERD and LPR, the head and neck distribution of the latter clearly separates these diseases as distinct entities warranting specialized focus and treatment.

Development of the movement of the epiglottis in infant and juvenile pigs.

Developmental change in a basicranial line and its relationship to the upper respiratory system in living primates.

TLDR
This study investigated the relationship between alterations in a basicranial line and changes in the upper respiratory system of selected non-human primates and of man through multivariate analysis of craniometric measurements, and compares the analytical results with previous postmortem findings on upper respiratory structure and function.

Developmental change in the position of the fetal human larynx.

TLDR
Results show that the upper and lower levels of the larynx correspond to the basiocciput and the lower border of the third to upperborder of the fourth cervical vertebrae, respectively.

Advances in understanding the relationship between the skull base and larynx with comments on the origins of speech

TLDR
Comparative and experimental studies of this region in mammals disparate from humans, and experimental work on the region in rats, is adding new data on how the larynx and skull base may functionally interact, adding new information on the mechanical relationship of the skull base to contiguous areas of the respiratory tract.

Function of the larynx in the fetus and newborn.

TLDR
There is clearly a need for wider use of techniques involving chronic instrumentation, particularly in the neonatal period, because the upper airway is involved in the regulation of tidal airflow, and it seems vital that the airway remains intact wherever possible.

Fossil Skulls and Hominid Vocal Tracts: New Approaches to Charting the Evolution of Human Speech

TLDR
The upper respiratory, or vocal, tract is the intersection of the authors' breathing, swallowing and vocalizing pathways and has a key role in determining the physical ability for vocal production.

Postnatal descent of the epiglottis in man. A preliminary report.

TLDR
Maturational descent of the epiglottis, found to occur between 4 and 6 months of age, is verified by cineradiography, and represents a discrete developmental event manifesting the potential for oral tidal respiration from a pattern of obligate nasal breathing.

The basicranium of fossil hominids as an indicator of their upper respiratory systems

TLDR
The craniometric analysis has shown that it is statistically improbable for the basicrania, and by extrapolation, upper respiratory systems of certain Neandertals to fall within the range of modern adult or sub-adult humans.

Effect of basicranial flexion on larynx and hyoid position in rats: An experimental study of skull and soft tissue interactions

TLDR
Results show induced basicranial flexion caused inferior displacement of the larynx and hyoid bone, thus indicating a direct, mechanical relationship between skeletal and soft tissues.

Position of the larynx in odontoceti (toothed whales)

TLDR
The results show that the upper respiratory tract of the odontocetes has evolved away from a basic mammalian pattern, allowing odontoketes to simultaneously swallow and echolocate.
