NERVES AND BLOOD SUPPLY
WHY…….With your partner provide a short description explaining the functions of our nerves.
EXTENSION TASK Part A– Identify the 2 different types of
nerves.Part B- Explain the differences between the 2 types.

AT1
Nerves carry electrical impulses to the brain which creates either Muscles Movement Secretion Action Sensation Stimulation
Motor nerves
Sensory nerves
Watching the link below identify and write down the
elements of the video in which there is
MOTOR nerve involvement and
SENSORY nerve involvement
You must write down as many elements of each as
possible

The body has 12 pairs of cranial nerves branching off from
the brain
In your group research which of the cranial nerves are relevant to
dental nurses.You must identify each of
these by- name
- roman numeral- supplied anatomical areas
Extension taskIf you complete this identify the function of the nerve

TRIGEMINAL NERVE
This nerve splits into 3 divisions
Name derives from this anatomical division 3 = “Tri”
What are these 3 divisions?
The Opthalmic nerve
Is a sensory nerve that supplies the eyeball, eyelid, skin of nose and forehead
The Maxillary Nerve –apple group
In your groups create a poster.You must clearly identify and label
-The anatomical path-Anatomical features (foramens)
-The teeth and surfaces supplied Extension task-On the study models clearly identify and
label each nerve providing a colour coded key
The Mandibular Nerve –cherry group

SCENARIOSWithin your groups you have
been provided with a scenario. You must allocated the job
roles of the dentist, the patient and dental nurse. Re-
enact your scenario to the group. You have 15 minutes to
prepare and rehearse.
AIMS To develop awareness of the nervous system of the
head and neck relevant to dental nurses. To increase understanding of local anaesthetic used
within the dental care setting.
OBJECTIVES O1-Outline the main characteristics of dental nerves. O2-Define the 4 cranial nerves relative to dental
nurses. O3-Identify and illustrate the maxillary and
mandibular nerves. O4-Recognise the syringe required to create
anaesthesia. O5-Summarise objectives 1,2,3,4 and present is a
simulation of dental scenarios.
