What are the three anatomical planes used to describe neural structures?
Sagittal, coronal, and transverse (horizontal) planes.
What are the main functional divisions of the nervous system?
CNS (brain and spinal cord) and PNS (somatic and autonomic systems).
What is the role of the autonomic nervous system?
Controls involuntary processes such as heart rate, digestion, and glandular activity.
What is kinesiology concerned with?
The assessment of movement, performance, and function in therapeutic and rehabilitative contexts.
What is rehabilitation in kinesiology?
Therapeutic intervention focused on maintaining, restoring, or enhancing movement for daily function.
What are the main areas of movement neuroscience?
Neurophysiology of movement, behavioral and psychological expressions, and neuroplasticity.
What characterizes normal human movement?
It is mostly autIomatic and coordinated, with volitional control emerging when patterns change or adapt.
What are the stages of behavioral movement expression?
Prenatal sensory motor development, postnatal sensory motor plasticity, and emergent conscious encoding via environment.
What is neuroplasticity?
The brain’s ability to reorganize and adapt structurally and functionally in response to experience or injury.
List the major parts of the brain and their primary roles.
Cerebrum (conscious thought and voluntary action), cerebellum (coordination), brainstem (vital autonomic control).
What percentage of neurons are contained in the cerebellum?
About 50% of all neurons in the brain.
What are the four main lobes of the cerebrum?
Frontal, parietal, temporal, and occipital lobes.
Where is the primary somatosensory cortex located?
In the postcentral gyrus of the parietal lobe.
What is the sensory homunculus?
A cortical map showing sensory input distribution for body regions.
Where is the primary motor cortex located?
In the precentral gyrus of the frontal lobe.
What is the motor homunculus?
A cortical map showing voluntary motor control distribution for body regions.
What are the three hierarchical centers of motor control?
Cognitive stage (cerebral hemispheres), associative stage (upper brainstem/diencephalon), and autonomous stage (pons, cerebellum, medulla).
What are the roles of these control stages?
Cognitive: planning; Associative: coordination; Autonomous: reflex and instinctive drives.
What is grey matter composed of?
Neuron cell bodies.
What is white matter composed of?
Myelinated axon fibers.
What is the main function of the white matter?
Transmission of nerve impulses between regions of the CNS.
What are commissural tracts?
Axons connecting gyri between the two cerebral hemispheres (e.g., corpus callosum).
What are association tracts?
Fibers connecting gyri within the same hemisphere.
What are projection tracts?
Fibers transmitting signals to and from lower parts of the CNS through the thalamus.
