ALREADY GRADED A+
the base or footplate of the stapes fits into the ____________________ - ANS-oval
widnow
the _________________ is divided into 3 areas : the semicircular canals, vestibule, an
dcochlea - ANS-bony labryinth
The _________________ is the oval central portion of the bony labryinth - ANS-
vestibule
At the end of each semicircular canal is a swollen enlargement called
the_____________ - ANS-ampulla
The only ting that connects the scala vestibuli and the scala tympani is the
___________ - ANS-helictrema
The _______________ separates the cochlear duct from the scala vestibuli - ANS-
vestibular membrane
The ________________ separates the cochlear duct from the scala tympani - ANS-
basilar membrane
_________________ is the maintenance of the position of the body relative to the force
of gravity - ANS-static equilibrium
_________________ is the maintenance of body position in response to sudden
movements such as rotational acceleration or deceleration - ANS-dynamic equilibrium
This si the thickened regions of utricle and saccule wall that act as receptors for static
equilibirum - ANS-macula
These glands secrete their products into ducts than carry the secretions into
body cavities, into the lumen of an organ, or to the outer surface of the body
ex: sudoriferous, sebaceous, mucous, and digestive glands - ANS-exocrine glands
, These glands secrete their products (hormones) into the interstitial fluid surrounding the
secretory cells rather than into ducts - ANS-endocrine glands
Local hormones that act on neighboring cells are called _____________ - ANS-
paracrines
What lipid-soluble hormone does this describe ?
-derived from cholesterol
- four rings at core
- large diversity of functions - ANS-steroid hormones
What lipid-soluble hormone does this describe ?
- presence of two benzene rings within a T3 or T4 molecule makes the VERY lipid-
soluble - ANS-thyroid hormones
What lipid-soluble hormone does this describe ?
-both a hormone and a NT
- catalyzed by the enzyme oxide synthase - ANS-Nitric oxide
What water-soluble hormone does this describe ?
-they retain an amino group - ANS-amine hormones
What water-soluble hormone does this describe ?
-protein hormones
- amino acid polymer
- Ex: oxytocin - ANS-peptide hormones
What water-soluble hormone does this describe ?
- derived from arachidonic acid and a 20-carbon fatty acid
- 2 types: prostaglandins and leukotrienes
- local hormones
- may act as circulating hormones - ANS-eicosanoid hormone
While msot water-soluble proteins are in a free form , lipid-soluble hormone molecules
are bound to ________________ - ANS-transport protein
What has these 3 functions?
