Flashcards in CHAPTER 1- Anatomy & Physiology of communication & swallowing Deck (80)
The bodily structure of an organism and its parts
The study of normal function of bodily structures & parts
The study of physiological, mechanical and psychological mechanisms of movement
the study of hearing disorders, evaluation, & rehabilitation
the study of how sound is used across languages to convey meaning
the study of mental processes & behavior
What are the 3 types of muscle cells?
1. skeletal 2. cardiac 3. smooth
Describe skeletal muscle
1. is striated & under voluntary control
2. generates voluntary muscle movements
Describe cardiac muscle
1. striated & contracts involuntarily
2. Found in the heart wall and contracts to propel blood through the heart chambers
Describe smooth muscle
1. no striated & contracts involuntarily
2. specialized for relatively slow, sustained contraction in the internal organs, blood vessels, eyes, and hair follicles
What is the complex information processing system that enables interaction with the environment for survival & reproduction?
Purpose of a neuron
information reception and transmission
Parts of a neuron
1. Cell body with nucleus
What is specialized for transmitting or propogating APs in order to communicate with other neurons contract muscle or cause glands to secrete
What is involved in processes specialized for receiving signals from other neurons or environmental stimuli?
The brain and the spinal cord make up the...
What is the PNS comprised of?
Spinal & cranial nerves
How can the PNS be subdivided?
somatic NS & autonomic NS
What is the function of the somatic NS?
supports sensation & motor functions of the body
What is the function of the autonomic NS?
regulates digestion, heart rate, blood pressure, digestion, respiration, & gland secretion
What are the two branches of the autonomic NS?
1. Parasympathetic division
2. Sympathetic division
Purpose of the parasympathetic division of the ANS?
helps maintain homeostasis by balancing functions such as respiration, digestion, & various metabolic needs
Purpose of the sympathetic division of the ANS?
fight or flight response- increases heart rate, blood pressure, sweat production, respiratory rate
How does the CNS communicate with the body?
via peripheral nerves (spinal & cranial)
How many pairs of cranial nerves are in the PNS?
How many pairs of spinal nerves are in the PNS?
Which cranial nerve contributes to the oral stage of swallowing: chewing, bolus sensation?
CN V- trigeminal
Which cranial nerve is responsible for hearing & sound localization?
CN 8- Vestibulocochlear
What cranial nerve is responsible for bolus manipulation and propulsion during the oral stage?
CN XII- Hypoglossal
