Special Senses Flashcards
Smell is also called
Olfactory
How many olfactory neurons are located in the olfactory epithelium
10 million
The olfactory pathway terminates in the olfactory cortex of the frontal or
Temporal lobe
The projections on the surface of the tongue are called
Papilla
Name sensory cells that are continuously replaced
Taste cells
Olfactory cells
What’s the normal life span of taste cells
10 days
What nerves transmit taste sensation
CN X vagus
CN IX glossopharyneal
CN VII Facial
The limbic and hypothalamus are considered…..
Secondary olfactory areas
Four major types of papillae
Filiform
Val late
Foliage
Fungiform
Most numerous papillae on the tongue but has no taste buds
Provides rough surface on the tongue allowing for manipulation of food
Filiform
Which cell in a taste bud is a sensory cell
Gustatory cells
Non sensory cells
Basal and supporting cells
Accessory eye structures
Conjunctiva
Lacrimal apparatus
Which nerve carries taste sensation from the epiglottis
CN X vagus nerve
Taste sensations are carried by three cranial nerves
Facial nerve CN VII
Glossopharynegeal nerve CN IX
Vagus nerve CN X
The central olfactory cortex areas are located in the
Temporal and frontal lobes
Conjunctiva
Mucus membrane protecting inner surface of eyelid and anterior surface of sclera
Lacrimal apparatus
Protect and lubricates the eyes through tears
Middle layer of eyeball wall
Vascular tunic
Palpebrae aka
Eyelids
Outer layer of the eyeball is
Fibrous tunic
White outer layer that protects internal eye structures, maintain eye shape, and provide attachment point for the extrinsic muscles of the eye
Sclera
Eyeball tunic layer order inner to outer
Nervous tunic
Vascular tunic
Fibrous tunic
Fibrous tunic
Sclera and cornea
