Anatomy and physiology of Voice and Speech

Extracts from this document...


Learning Outcome 1 Anatomy and physiology of Voice and Speech HNC Acting and Performance Alignment 1) Alignment is the way in which the body holds itself. The position of the skeletal frame which affects posture. 2) As an actor awareness of good alignment is important because it affects the way you breathe and your voice. Also it makes it easier to see what adjustments need to be made when portraying a character. 3) Cervical Thoracic Lumbar Sacrum Coccyx 4) There are various different areas that we need to look at in order to work towards a more effective alignment. An example of a good stance would be: Feet hip width apart, and parallel with each other Feet contacting the floor at the heel, the outer edge and the ball Pressing the weight down onto the feet Knees released or loose Pelvis central - not tipped to the back or front Energy rising up through the lower spine to the head Chest and ribs ...read more.


The Alexander Technique is used to help to teach people about how efficiently and effortlessly they can use their bodies in everyday life. Often, we develop bad posture and habits without being aware of this, and expend too much energy or muscle force to achieve a task. Alexander Technique teachers help to adjust the client's posture to recognise the difference between current habits and what it feels like to use muscles with minimum effort and in a relaxed, fluid way. The Technique teaches how to become more aware of your own posture, balance and movement in everyday life. Learning Outcome 1 Anatomy and physiology of Voice and Speech HNC Acting and Performance Breathing 1) The principal bony structures involved in the breathing process are the ribs, spine and breast bone. 2) The primary muscles used in breathing are the Diaphragm, Abdominal (rectus abdominis) and muscles of the ribs (external intercostals). 3) The diaphragm is a large dome shaped muscle located under the rib cage. ...read more.


7) As an actor we use breathing exercises to control and regulate our breathing. Also for reducing stress and obtaining a relaxed clear state of mind. 8) Breath counting: Sit in a comfortable position with the spine straight and head inclined slightly forward. Close your eyes and take a few deep breaths. Then let the breath come naturally without trying to influence it. Begin the exercise by counting 1 to yourself as you exhale. The next time you exhale, count 2 and keep doing it till you get to the highest number you possibly can. 9) The respiratory cycle is made up of inspiration and expiration. Inspiration begins with the contraction of the diaphragm resulting in an increase in negative pressure; this negative pressure generates airflow because of the pressure differences in the atmosphere, air enter, inflating the lung through the mouth or nose. Expiration is the movement of air out of the bronchial tubes, through the airways and back out through the mouth or nose. Exhaled air is rich in carbon dioxide and is the waste product of the respiratory cycle. ...read more.
