Cranial nerve mnemonics to remember the names of the nerves in order include: On old Olympus’s towering top, a Finn and German viewed some hops. Ooh, ooh, ooh to touch and feel very good velvet.
How do you remember the peripheral nervous system?
When assessing the distal peripheral nerve motor functions of the hand, try using this mnemonic: “Rock, Paper, Scissors”. The combinations of movements by muscles innervated by the three peripheral nerves make up the gestures of “Rock, Paper, Scissors”.
What are the 12 cranial nerve?
In higher vertebrates (reptiles, birds, mammals) there are 12 pairs of cranial nerves: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V), abducent (or abducens; CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), accessory (CN XI), and …
Is oculomotor sensory or motor?
Somatic Motor
| Nerves in Order | Modality | Function |
|---|---|---|
| Olfactory | Special Sensory | Smell |
| Optic | Special Sensory | Vision |
| Oculomotor | Somatic Motor Visceral Motor | Levator palpebrae, superioris, superior, medial & inferior recti muscles Parasympathetic to ciliary & pupillary constrictor muscles |
| Trochlear | Somatic Motor | Superior oblique muscle |
What does CN 9 do?
The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.

What are the 3 divisions of the PNS?
Sensory: Connects the brain and spinal cord to your skin and allow you to feel pain and other sensations. Autonomic: Controls involuntary function (e.g., blood pressure, digestion, heart rate). Motor: Connects the brain and spinal cord to muscles to stimulate movement.
What does the term afferent refer to?
nerves that carry signals toward the central nervous system from the periphery. Afferent may also be used generally to describe nerves that are traveling into a nervous system structure (i.e. input fibers for a particular area as opposed to output fibers).
What does afferent mean?
afferent – a nerve that passes impulses from receptors toward or to the central nervous system. afferent nerve, sensory nerve. dorsal horn, dorsal root – one of the two roots of a spinal nerve that passes dorsally to the spinal cord and that consists of sensory fibers.
What is the function of an afferent nerve?
The afferent nerve is typically responsible for relaying sensory information from the periphery (e.g. the skin) to the spine. This could include information like pain, temperature, vibration, etcetera. They (the afferent nerves) work in close collaboration with the efferent nerves, which are responsible for motor programmes.
What is the definition of efferent?
Directed away from a central organ or section. 2. Carrying impulses from the central nervous system to an effector. n. An efferent organ or body part, such as a blood vessel. [From Latin efferēns, efferent-, present participle of efferre, to carry off : ex-, ex- + ferre, to carry; see bher- in Indo-European roots .]
