Describe the difference between hemiballismus and athetosis:
Hemi= violent thrashing of the contralateral extremity vs. Athe= slow, failing upper and lower extremities, aimless movements.

Function of the somatic nervous system:
Involuntary control of the body movements

2 significant fissures of the brain:

Cranial nerves, autonomic nervous system (ANS), and somatic nervous system (SNS)
Autonomic nervous system (ANS), and somatic nervous system (SNS)
Functions of the occipital lobes:
Visual interpretation from optic pathway, color, form, motion

Function of the thalamus:
Receives and relays, receives sensation from sensory receptors, relays sensory information to the cortex except olfaction, receives motor from cerebral hemispheres, relays motor to motor receptors “square-shaped”
Receives and relays, receives sensation from sensory receptors, relays sensory information to the cortex except olfaction, receives motor from cerebral hemispheres, relays motor to motor receptors “egg-shaped”
What is the difference between gray and white matter:
White Matter (surface of the cerebrum and cerebellum, forms nuclei body, basal ganglia, grayish in color, contains nerve cell bodies, non-myelinated), Gray Matter (beneath the gray matter, myelinated neuronal axons)
Gray Matter (surface of the cerebrum and cerebellum, forms nuclei body, basal ganglia, grayish in color, contains nerve cell bodies, non-myelinated), White Matter (beneath the gray matter, myelinated neuronal axons)

Occur during involuntary movement of a limb to increase as tremors as it nears its intended goal
Parts of the Diencephalon:
Epithalamus, thalamus, hypothalamus, hippocampus
Epithalamus, thalamus, hypothalamus, subthalamus

Function of precentral gyrus:
Voluntary movement
Involuntary movement
3 layers of the meninges:
Pia mater, dura mater, arachnoid mater
Pie mater, dope mater, arachnoid mater
Describe dysdiadochokinesia:
impaired ability to perform rapid alternating movements. Loss of coordination with movement.
Occur during voluntary movement of a limb to increase as tremors as it nears its intended goal
Function of the central sulcus:
Separates the occipital and temporal lobes (separates the primary motor M1 and primary somatosensory cortex SS1)
Separates the frontal and parietal lobes (separates the primary motor M1 and primary somatosensory cortex SS1)

Cerebral lobes, cerebellum, basal ganglia, diencephalon, brainstem, limbic system
Cerebral lobes, temporal lobes, basal ganglia, diencephalon, brainstem, limbic system
Functions of the parietal lobes:
Sensory detection, perception, interpretation (posterior to the frontal lobes, central sulcus divides parietal from frontal lobes, parieto-occipital sulcus posterior border, lateral fissure inferior border)
Motor detection, perception, interpretation (inferior to the temporal lobes, central sulcus divides occipital from frontal lobes, parieto-occipital sulcus posterior border, medial fissure inferior border)
3 lobes of the cerebellum:
Flocculonodular, anterior, posterior
Flocculonodular, anterior, lateral
Describe decomposition of movement:
Overshooting
Movement patterns are performed in parts rather than smooth, singular motion

Uncoordinated patterns of movement that affect gait, posture, and UE motor control.
Coordinated patterns of movement that affect gait, posture, and LE motor control.
Describe dyskinesia:
Rhythmic, repetitive movements that have an odd quality. Can occur in face, mouth, jaw and tongue vs. limbs (due to a basal ganglia lesion)
