The document discusses the examination of the motor system including inspection of body posture, gait, muscles, reflexes, and strength. It describes normal reflexes like superficial skin reflexes and deep tendon reflexes. It then discusses the effects of lesions in different parts of the motor system including the cortex, internal capsule, brainstem, spinal cord, and peripheral nerves. Lesions can cause symptoms like paresis, hyperreflexia, pathological reflexes, and changes in muscle tone and strength. The location of the lesion determines whether symptoms present on one side of the body or both sides.

Human reflexes
Definition: It is involuntary response of an organ to a stimulus.
- It is the arrangement of neurons through which the reflex is carried out.
- It is usually formed of:
Afferent (sensory) neuron.
2) An interneuron (may be absent).
3) nerve center (cell body of the efferent neuron).
4) Efferent (motor) neuron.

Feeding plate for a newborn with Cleft Palate.pptxSatvikaPrasad
A feeding plate is a prosthetic device used for newborns with a cleft palate to assist in feeding and improve nutrition intake. From a prosthodontic perspective, this plate acts as a barrier between the oral and nasal cavities, facilitating effective sucking and swallowing by providing a more normal anatomical structure. It helps to prevent milk from entering the nasal passage, thereby reducing the risk of aspiration and enhancing the infant's ability to feed efficiently. The feeding plate also aids in the development of the oral muscles and can contribute to better growth and weight gain. Its custom fabrication and proper fitting by a prosthodontist are crucial for ensuring comfort and functionality, as well as for minimizing potential complications. Early intervention with a feeding plate can significantly improve the quality of life for both the infant and the parents.
2. The first neuron is located in
cortex.
The second neuron is located
in the anterior horn on the
spinal cord

4. THE EXAMINATION OF THE MOTOR
SYSTEM
• body pose
• gait
• involuntary movements
• inspection and palpation of muscles
• normal reflexes
• muscle tone
• muscle strength (force)
10. Normal reflexes
I. Superficial reflexes arise irritation of at skin, a
cornea, mucous membranes-
A. From mucous membranes
• Corneal
• A reflex from the soft palate
• Pharyngeal
B. From skin
• Abdominal jerks(upper, middle, lower)
• Plantar reflex
• Cremasteric reflex
• Anal reflex
11. Normal reflexes
II. Deep reflexes are usually caused at impact
percussion hammer on tendon-
• Biceps reflex
• Triceps reflex
• Knee reflex
• Tendon (Achilles) reflex
III. Periosteal reflexes is arisen at impact on the
periosteum-
• Carporadial reflex
12. THE AFFECTION OF THE MOTOR SYSTEM
Total absence of any movements is called as a paralysis or palsy
The restriction of volume of movements and decrease in force is paresis
Kinds of the paralysis (paresis)
monoplegia diplegia triplegia tetraplegia
(monoparesis) (diparesis) (triparesis) (tetraparesis)
paraplegia
(paraparesis)
hemiplegia
(hemiparesis)
13. THE SYMPTOMS OF THE CENTRAL PARESIS
• muscular hypertension
• decrease of muscular force
• hyperreflexia
• clonus
• pathological reflexes
• protective reflexes
• decrease or absence of skin reflexes
• the dysfunction of the urination and dejection
14. MUSCULAR HYPERTENSION (RIGIDITY)
The tone is raised on spastic type and muscular resistance is
felt at the beginning of movement (a clasp-knife sign). The
tone raises in flexors of hands and extensors of legs (the
Wernicke-Mann’s pose)
15. MUSCULAR HYPERTENSION
The slight paresis recognizes with help Barre’s test. A patient
must raise extremities and hold their at closed eyes. On a side
of a lesion extremity falls down.
16. DECREASE OF MUSCULAR FORCE
GRADING OF FORCE:
0 numbers No muscle contraction visible, complete paralysis.
1 number Muscle contraction visible, but no movement of joint.
2 numbers Movement is possible when gravity is excluded i.e. patient ' can
move limb horizontally on bed but unable to elevate.
3 numbers Movement possible against gravity but not against resistance
i.e. when patient is asked to elevate the limb he is able to
elevate, however not able to move the limb if further resistance-
is added.
4 numbers Movement, is possible against gravity and some, resistance.
5 numbers Normal power.
17. CLONUS
Clonus is the term applied to a rhythmic series of involuntary muscle contractions
evoked by sudden stretch of the muscle. Clonus can be evoked on ankle and knee as
following:
Ankle clonus
Support the flexed knee with one hand in the popliteal fossa so that the ankle rests
gently, on the bed. Using the other hand arid briskly dorsiflex the foot and sustain
the pressure, there will be a rhythmical beating (alternate plantar, flexion and
dorsiflexion) of the foot for as long as the pressure is maintained.
Knee clonus
Sharply push the patella towards the foot while the patient lies supine and relaxed
and the knee extended. Following the initial jerk, exert sustained pressure with the
thumb and index finger in a downward direction on the patella, the patella will jerk
up and down.
18. PATHOLOGICAL REFLEXES
Pathological reflexes
Carpal pathological reflexes are
characterized by slow bending
fingers of a hand:
- Rossolimo’s reflex
- Zhukovsky's reflex
- Bechterew-Mendel’s reflex
- Jakobson-Lask’s feflex
Plantar pathological reflexes are
divided on flexor and extensor ones.
Flexor reflexes are
characterized by slow flexion of
foot fingers:
- Rossolimo’s reflex
- Zhukovsky's reflex
- Bechterew’s reflex
Extensor reflexes are characterized
by occurrence extension of the big
finger and a fanlike divergence of other
fingers:
- Babinski's reflex
- Oppenheim's reflex
- Gordon's reflex
- Schäffer's reflex
- Puusepp's reflex
19. CARPAL PATHOLOGICAL REFLEXES
Rossolimo’s reflex - flexion
of 2-5 fingers of a hand at
short, fast impacts on
finger-cushion.
Zhukovsky's reflex –
impact at the middle of a
palm of the patient.
Bechterew-Mendel’s reflex
– impact by the dorsal part
of a wrist of the patient.
Jakobson-Lask’s feflex -
percussion on styloid process of
ulna.
20. PLANTAR PATHOLOGICAL REFLEXES
Flexor reflexes
Rossolimo’s reflex - flexion of
2-5 fingers of a hand at short,
fast impacts on finger-cushion.
Zhukovsky's reflex -
percussion on the middle of a
sole.
Bechterew’s reflex -
percussion on the dorsal
part of the foot.
21. PLANTAR PATHOLOGICAL REFLEXES
Extensor reflexes
Babinski's reflex -
irritation of the
external edge of a
sole.
Oppenheim's reflex –
pressing on an
anterior surface of a
tibia ridge.
Gordon's reflex –
compression of the
gastrocnemius muscle of
the patient.
Schäffer's reflex –
compression of the
Achilles' tendon.
Puusepp's reflex – a fan-
shaped divergence of 2-5
fingers at irritation of a
sole.
22. PROTECTIVE REFLEXES
At irritation of the paralysed extremity a patient
pulls aside this extremity to yourself (Mari – Fua’s
symptom).
23. THE SYMPTOMS OF THE PERIPHERAL PARESIS
• hypotonia (atonia)
• hyporeflexia (areflexia)
• hypotrophy (atrophy)
• fibrillation and fasciculation
24. LESION OF A CEREBRAL CORTEX
A lesion involving the cerebral
cortex, such as a tumor, an infarct or a
traumatic injury, causes weakness or
paresis on the opposite side. At
irritation lesion can be the cause focal
(jacksonian) seizures.
If focus is located in a
paracentral part of a cortex,
then a patient has weakness or
paresis in both legs.
25. LESION OF AN INTERNAL CAPSULE
If the internal capsule is involved, there will be a
contralateral spastic hemiplegia with the central paresis of
7th and 12th pairs of the cranial nerves and the Wernicke-
Mann’s pose.
+
26. LESION OF A BRAINSTEM
At affection of brainstem causes alternating (cross)
syndromes. That is the affection of the cranial nerves on
the affected side and hemiplegia on the opposite side.
