Flashcards in Anatomy- The Autonomic Nervous System Deck (19):
1

Parasympathetic

"Rest & digest"

- low energy use, digestion of food

2

Sympathetic

"Fight or Flight"

Rapid heart rate and breathing rate

3

Taste buds

About 10,000 in adult human;

Most taste buds are located within the papillae(projections of the tongue mucosa)

4

Eye---fibrous Tunic:

Dense, a vascular, 2 regions

5

Sclera

The white of the eye

6

Cornea

Name the 2 layers

Anterior is 1/6 of fibrous tunic

2 layers: stratified squamous epithelium on the outside and simple squamous epithelium on the inside.

7

Sensory tunic( Retina): consists of 2 layers

Pigmented layer and inner neural layer

8

Rods:

Grey, black and white

9

Cones:

Color

10

Bipolar cells:

They can synapse with either rods or cones (but not both)The bipolar cells then transmit the signals from the photoreceptors or the horizontal cells, and pass it on to the ganglion cells directly or indirectly.

11

Ganglion cells

Receive input from bipolar cells & their axons

12

Blind spot( optic disc)

Location on retina where the optic nerve exits eye

13

Fovea Centralis

Only cones present; region of greatest visual acuity

14

Cones have 3 different types of opsins to use:

Red cone, green cone, blue cone.

15

Outer Ear consists of______ & ______.

Auricle(pinna) and the external auditor canal

16

Tympanic membrane(eardrum) -

vibrates with frequency of sound waves, transfers vibrations to middle ear.

17

3 ossicles(small bones) of the Tympanic cavity

Malleus(hammer)- attaches to eardrum

Incus(anvil)

Stapes(stirrup)- attaches to oval window of vestibule.

18

Vestibule is composed two sacs:

Saccule & Utricle

19

Autonomic Nervous System:

System of motor neurons within the motor division of the peripheral nervous system that inner area smooth may lead, cardiac muscle and glands.
