DAANCE Module 1 Graded A+
Neurons and Nervous System
- Neurons: ✔️ Cells of the nervous system.
- Action Potential: ✔️ The nerve's threshold of stimuli.
- Terminal Button: ✔️ The bulge at the end of the nerve that touches the next nerve.
- Synaptic Cleft: ✔️ The gap between two nerves that impulses must cross at the synapse.
- Cerebral Cortex: ✔️ Responsible for thought, learning, memory, consciousness, and sensations such
as pain and heat.
- Cerebellum: ✔️ Center for motor function.
- Medulla Oblongata: ✔️ Control center for maintenance of blood pressure, pulse, and respiration; an
autonomic center.
- Central Nervous System (CNS): ✔️ Composed of the brain and spinal cord.
- Peripheral Nervous System (PNS): ✔️ Composed of sensory and motor nerves.
### Cranial Nerves
- Cranial Nerves:
- Olfactory (1st): Smell
- Optic (2nd): Vision
, - Trigeminal (5th): Sensation in teeth and jaw
- Facial (7th): Facial expression
- Auditory (8th): Hearing
### Anesthesia Techniques
- Mandibular Block: ✔️ Anesthetizes all mandibular teeth, chin, and lip on the same side.
- Posterior Superior Alveolar Block: ✔️ Anesthetizes the branches for the posterior portion of the
maxillary alveolus.
### Cardiovascular System
- Myocardium: ✔️ Heart muscle capable of pumping approximately 5 quarts of blood per minute.
- Autonomic Nervous System: ✔️ Regulates involuntary functions, such as breathing and heart rate.
- Homeostasis: ✔️ A constant state of internal balance.
### Autonomic Nervous System
- Sympathetic System: ✔️ Speeds up body functions (fight or flight response).
- Parasympathetic System: ✔️ Slows down body functions (rest and digest).
- Baroreceptors: ✔️ Receptors in the walls of the aorta and carotid arteries that respond to increased
pressure by decreasing sympathetic output and increasing parasympathetic output, thereby decreasing
heart rate and blood pressure.
