Intro to Movement Neuroscience
Lecture #1: Introduction to Neuroscience
Neuroscience is based on the functional anatomy of the nervous system
There are neuroanatomical, neurophysiological, and cognitive/behavioural
aspects of human movement.
Levels of neuroscience include…
1. Molecular neuroscience
2. Cellular “ “
3. Systems “ “
4. Behavioural “ “
5. Cognitive “ “
Introduction to Neuroanatomy
Four regions of the nervous system…
1. Peripheral
2. Spinal
3. Cerebrum
4. Cerebellum
PNS → nervous system structures not included in the brain and spinal cord. Ex:
medial, sciatic, ulnar, radial nerves
CNS→ spinal cord, cerebellum and cerebral regions, and brainstem.
Cerebrum: intelligence, process information
Cerebellum: Coordination, regulation
The 3 systems involved in these regions…
1. Somatosensory
❖ Periphery to the brain
2. Somatic Motor
❖ Brain to the skeletal muscles
3. Autonomic
❖ Brain and viscera (smooth muscle, cardiac muscle, glands)
❖ Maintain homeostasis

Intro to Movement Neuroscience
Peripheral Region
Afferent axons → information to the brain (think of ‘A’ as in arrives at the brain)
When we touch a subject
Efferent axons → information away from the brain
Making appropriate movement
Somatic nervous system→ cell bodies are contained in the brain and spinal cord
(CNS)
Autonomic nervous system→ cell bodies are outside of the spinal column and
brain (in sympathetic trunk)
The Spinal Cord
Spinal cord has meninges covering it. → the meninges contains cerebrospinal
fluid
Spinal nerve separates each side of the spinal cord (2)
Spinal cord extends from foramen magnum to L1-L2
The spinal cord has 31 segments with a pair of spinal nerves branching from
each segment
The Spinal cord ends distally at the Conus medularis
Cauda Equina (horsetail)→ Where epidurals are performed
Filum Terminalae: CT that connects to the sacrum and coccyx
Internal Anatomy of the Spinal Cord
Ventral (Front)→ contains motor pathways
Sensory info exits the CNS from the ventral end and down the spinal cord
Dorsal (back) → contains sensory pathways
