- BCancellous bone
4The bone that the skull is composed of is made from a ______ interior.
- ACompact bone
- BCancellous bone
5Sutures are connected by what fibrous substance?

- EOccipital
- FLacrimal
- GEthmoid
7What is the feature on the axis vertebrae which helps to allow the atlas and skull to rotate?
- ADens

8In the myotatic reflex, is the sensory input from the muscle spindle excitatory to the motor neuron in the spinal cord or inhibitory? Why?
- AExcitatory - this leads to contraction of the muscle which prevents damage that may be caused by stretch of the muscle when excess strain is placed on it.
- BInhibitory - this leads to absence of excitatory contractory signals and therefore the muscle relaxes. This helps to prevent damage to the muscle.
9In the reverse myotatic reflex, the golgi tendon organ will send out inhibitory signals to the interneuron to therefore co-ordinate relaxation of the muscle.
- AVerdadero
- BFalso
10In the knee jerk reflex, an inhibitory interneurone leads to relaxation of the quadriceps.
- AVerdadero
- BFalso
11In the crossed extensor reflex, excitatory efferent signals travel to the quadriceps of the leg that is taking body weight.
- AVerdadero
- BFalso
12The jaw jerk reflex is an example of the myotatic reflex in action.
- AVerdadero
- BFalso
13The gag reflex is processed by what cranial nerve?
- AHypoglossal
- BGlossopharyngeal
- CVagus
- DTrigeminal
14The motor action co-ordinated by CN IX leads to contraction of what muscles?
- ALaryngeal
- BTongue
- CSternocleidomastoid
- DSternohyoid
15Sensory afferent information associated with the swallowing reflex travels to what brain centre in the brain stem?
- AThe swallowing centre
- BThe masticatory central pattern generator
- CThe solitary nucleus
16Peristalsis is an enteric reflex.
