Hydromyelia
In hydromyelia, there is dilatation of the central canal of the spinal cord. The dilatation is lined by the normal ependymal lining of the central canal.
The term can refer to dilatation of the persistent central canal of the spinal cord which communicates with the fourth ventricle (cavity wall...

Anterior corticospinal tract
The anterior corticospinal tract is formed at the level of the of the medullary pyramids, where the majority (90%) of descending corticospinal tract fibres decussate to form the lateral corticospinal tract. The majority of the remaining non-decussating 10% of fibres form the much smaller anterio...

Lateral corticospinal tract
The lateral corticospinal tract is formed at the level of the of the medullary pyramids when the majority (90%) of descending corticospinal tract fibres decussate. The remaining 10% do not decussate and form the much smaller anterior corticospinal tract. A few non-decussated fibres may enter the...

Spinocerebellar tract
The spinocerebellar tracts are afferent neurones that convey proprioceptive data from the spinal cord to the cerebellum. There are anterior and posterior spinocerebellar tracts, also eponymously named the Gowers tract and Flechsig tract respectively. Both the anterior and posterior spinocerebell...

Corticorubral tract
The corticorubral tract contains neurones that connect the primary motor and sensory areas to the red nucleus. The rubrospinal tract then descends through the spinal cord.
The tract is thought to excite flexor muscles and inhibit extensor muscles.

Rubrospinal tract
The rubrospinal tract contains neurones that carry signals from the corticorubral tract. The tract is thought to excite flexor muscles and inhibit extensor muscles.

Central connections
The magnocellular portion of the red nucleus gives rise to the rubrospinal tract. It decussate...

Lateral spinothalamic tract
The lateral spinothalamic tract, also known as the lateral spinothalamic fasciculus, is an ascending pathway located anterolaterally within the peripheral white matter of the spinal cord. It is primarily responsible for transmitting pain and temperature as well as coarse touch.
The anterior sp...

Anterior spinothalamic tract
The anterior spinothalamic tract, also known as the ventral spinothalamic fasciculus, is an ascending pathway located anteriorly within the spinal cord, primarily responsible for transmitting coarse touch and pressure.
The lateral spinothalamic tract (discussed separately), in contrast, primar...

Denticulate ligaments
The denticulate ligaments are bilateral triangular lateral extensions of pia mater that anchor the spinal cord to the dura mater.
They are formed by pia mater of the spinal cord coursing in-between the dorsal and ventral nerve roots bilaterally. They function to provide stability to the spinal ...
