Anatomy Flashcards
Classifications for the respiratory system
Conducting portion and respiratory portion
Nose, pharynx, larynx, trachea, bronchi, bronchiales, terminal bronchioles
Conducting portion
Respiratory Bronchiole, aveolar duct, alveolar sac and alveoli
respiratory portion
Upper Respiratory tract
Nose and pharynx
lower respiratory tract
Larynx, trachea, Bronchi and lungs
Active contraction of the diaphragm
inhalation
When does the diaphragm flatten
when contracted
what elevates the ribs
contraction
when does the diaphragm become more domed shaped
when it relaxes
Thoracic walls
- Superior
- Inferior
- Lateral
- Anterior
- Posterior
- Superior: Thoracic inlet
- Inferior: Diaphragm
- Lateral: ribs
- Anterior: Manubrium and sternum
- Posterior: thoracic vertebrae
True Ribs:
False ribs: and where they attach
Floating Ribs:
True: 1-7 and vertebra to sternum
False: attach at 7th rib’s cartilage
floating 11-12 only attach at vertebrae
Olfaction occurs
in the olfactory mucosa in the superior 1/3 of the nasal cavity
Olfaction is caused by
hairlike projections from the olfactory bulb(CN 1) from the cranial cavity to the ethmoid bone
what is the cribriform plate
area where the hairlike projections pass through from cranial cavity to the ethmoid bone.
Frontal Sinus
Ethmoid sinus
Maxillary Sinus
Boundaries of the nasal cavity
roof
anterior to posterior
Nasal, frontal, ethmoid, sphenoid
Boundaries of the nasal cavity
Floor
anterior to posterior
Maxilla and palatine
Boundaries of the nasal cavity
Medial
anterior to posterior
Septal Cartilage, vomer and ethmoid bone
Lateral of the nasal cavity
