There are different physical aspects of your vocal utility and talents.
Your body is a wonderful enabler of speech process and outcome.
There is great interplay of a couple of individual and collective “organs” if you will, to effect speech.
We take a quick, brief overview at some of them.
- It can be found at the top ring of the windpipe, the two shield cartilages, and epiglottis or lid.
- It contains the voice-box and vocal cords for producing sounds
- The cavity into which the mouth and nose open
- Mouth of the larynx (membranous or muscular crevice)
- The edges of the larynx which constitute the vocal cords or glottis lips.
The vocal cords:
- Often described as two slight, elastic bands
- They are both situated in the larynx,
- Immediately below the “Adam’s apple.”
- To produce sound they vibrate and are thrust forward into the air-stream escaping from the lungs
The trachea or windpipe:
- A cylindrical, cartilaginous and membranous tube
- It is the common air passage to the lungs
- Partly situated in the neck and partly in the chest area
- Measures about four and a half inches in length.
- The lid of the glottis
- Protective functioning mainly
- Prevents all foreign bodies from entering the larynx
- When you breathe it is raised
- It closes to allow food to pass over it into the gullet
The ‘Articulate/Articulation’ organs:
- Tongue, teeth and lips
Your Beating Heart:
- This muscle-organ is situated between the two lungs under the breast-bone, slightly inclined and positioned to the left.
- It mainly functions to regulate the passage of the blood;
- After passing through the lungs, the blood then passes through to the outmost outposts and extremities of the body
- Circulates through the heart to repeat the process all over again.
Your chest area and its surrounding cavities
- The chest-area can easily be spotted. (put your hand on your heart) and you are right there!
- It is that part of your upper torso that is formed by the backbone, ribs, breast-bone and collar-bone.
- It is lined and covered with membranes
- It is supported and worked by muscles.
- Vital organs like the lungs, heart and principal arteries and veins are found here.
Capacity of lungs/lungs:
- Lungs are vital organs to effect and enable life. You need to breathe and take in air to survive
- Your organs known as ‘lungs’ are conical shaped,
- They are made up of five lobes, honeycombed with hexagonal cells of various sizes
- Their main purpose is to contain air.
- Form and function work together to supply oxygen to, and take up carbon from, the blood.
The soft palate:
- The curtain at the back of the mouth (membranous, muscular)
- Partitioning the mouth below and the nasal passages above it.
The functions of soft palate are:
UP: When it is raised as high as possible, it closes the opening from the back of the mouth to the nostrils; the vocal current then finds its way and passes out entirely through the mouth
DOWN: When it is allowed to fall upon the tongue, the passage to the mouth is closed, and the vocal current escapes by the nostrils, producing a nasal tone
- This is the pendent portion of the soft palate.
The hard palate:
- The hard portion of the roof of the mouth
- It is above the upper teeth.
- This consists of two muscles and a central tendon, with a slanting direction from the breastbone to the loins.
- It forms a foundation on which the lungs rest (convex) and partitioning them from the abdominal organs (concave).
- It contracts, pressing the abdominal organs downward and outward,
- It makes room for the lungs to expand when you inhale.
- When you exhale it returns to its original spot and shape.
- It draws air out and allows the lungs to ‘collapse’ back to its rested state (deflate).
- It is like the bellows on an organ.
