Which tonic/brainstem reflex begins at birth and is integrated at 4-6 months; is stimulated when the head is rotated to one side; and its response is for the patient to assume a "fencing posture"?

- Symmetrical Tonic Neck Reflex (STNR)
- Asymmetrical Tonic Neck Reflex (ATNR)
- Neck Righting on Body
- Crossed Extension
Asymmetrical Tonic Neck Reflex (ATNR)
The Moro Reflex onset begins at 28 weeks and is integrated at 5-6 months. To test the reflex,
the clinician carefully drops the head in supported supine position. What is the expected response?

A. Extension of UEs or Les to hold the position
B. Flexion of one LE elicits extension of the opposite LE
C. Abduction and extension of arms followed by flexion adduction of arms across chest.
D. The whole body turns
C. Abduction and extension of arms followed by flexion adduction of arms across chest.
Which reflex is characterized by fingers maintaining flexion with pressure to the palm? Its onset is at birth and it is integrated at 4-6 months?

- Traction
- Plantar grasp
- Palmer grasp
- Tonic Labyrinthe
Palmer grasp

- Neck Righting on the Body
- Equilibrium Reflexes
- Protective Reflexes
- Optical Righting
Neck Righting on the Body
Which reflex is characterized by the following: if the patient is positioned prone, they will demonstrate an overall flexion pattern and If the patient is positioned supine, they will demonstrate an overall extension pattern?

- Tonic Labyrinthine
- STNR
- Equilibrium Reaction
- Body Righting on Body

When does the Protective Extension backwards BEGIN?

A. 4 months
B. 9-10 months
C. 9-12 months
D. 12-24 months
9-10 months
What response is expected in the Symmetrical Tonic Neck Reflex (STNR) after the stimulus of flexion of the head?

- Assumption of fencing posture
- Extension and abduction of the limbs to protect and support the body
- The head orients to vertical
- The arms flex and legs extend
The arms flex and legs extend
Which reflexes are characterized by the body's response of the UEs or LEs to hold a position in response to pressure from a supporting surface to an arm or foot?

- Supporting Reactions
- Protective Extensions
- Equilibrium Reactions
- Body Righting Reactions
Supporting Reactions
Which of the following statements describes the volitional movement most accurately?

- It starts with a command in the motor cortex, goes to the spinal cord and is turned into reflexive type of movement from there

- It starts at the cerebellum and is fed through the basal ganglia where sensory input is integrated and then the desired automatic movement is executed

- It starts in the motor cortex, travels down the lateral corticospinal tract to the lower motor neurons. During this process, sensory feedback is processed by the cerebellum to make movement smooth

- Quick stretch to muscle belly
- Slow stroking of muscle belly
- Fast stroking of muscle belly
Slow stroking of muscle belly
In order to facilitate the standing position using tactile cues, the following hand placement is appropriate:

- Pushing in posterior direction with a hand on gluts and an anterior direction with a hand at sternum

- Pushing in a posterior direction on the tibias and a anterior direction with the hands on the mid back.

- Pushing in an anterior direction with a hand on gluts and a posterior direction with hand at sternum

Tapping of a muscle belly
What is always an upper motor neuron sign (CNS)?

- Hyporeflexia
- Weakness
- Spasticity
- Diminished reflexes

The peripheral nervous system is better at repairing itself for all of the following reasons EXCEPT:

- The axons are better at regenerating themselves

- The peripheral system produces neurite outgrowth inhibitory factor (NOGO)

- The peripheral system produces neurite growth factor

- The axons are myelinated by Scwann cells
The peripheral system produces neurite outgrowth inhibitory factor (NOGO)
The following is true of motor units EXCEPT:

- The motor unit fires in all or nothing fashion as all muscle fibers associated with the motor unit will fire.

- The primary neurotransmitter released at the neuromuscular junction is achetocholine (Ach).

- A motor unit consists of the neuron, axon and all of the muscle fibers it innervates

- A motor unit is a "plan" run by the brain and initiated in the motor cortex
