TRACTS OF THE SPINAL CORD

  Tracts of the Spinal Cord   consist of fiber bundles that have a common origin and a common termination are somatotopically organized. are divided into ascending and descending pathways.   Ascending Spinal Tracts represent functional pathways that convey sensory information from soma or viscera to higher levels of the neuraxis.   usually consist of […]

thalamus

Thalamus

Thalamus is the largest division of the diencephalon.   receives precortical input from all sensory systems except the olfactory system.   receives its largest input from the cerebral cortex.   projects primarily to the cerebral cortex and to a lesser degree to the basal ganglia and hypothalamus.   plays an important role in sensory and […]

Spinal cord

Spinal cord

  Spinal Cord   weighs about 30 g, comprising 2% of the weight of the adult brain.   averages, in length, 45 cm in males and 42 cm in females. extends, in adults, from the foramen magnum to the lower border of the first lumbar vertebra (MCQ)   extends in newborns, it extends to the […]

Olfactory Gustatory and Limbic system

Olfactory Gustatory and Limbic system

mediates the special visceral afferent (SVA) modality of smell via the olfactory nerve (CN I). is the only sensory system that has no precortical relay in the thalamus. projects to the thalamus, hypothalamus, amygdala, and hippocampal formation. Olfactory pathway   Olfactory receptor cells   are chemoreceptors. number 25 million on each side. are replaced throughout […]

Meninges and CSF

Meninges and CSF

Meninges include pia mater and the arachnoid (together known as the leptomeninges)   dura mater (pachymeninx).   Pia mater is a delicate, highly vascular layer of connective tissue.   closely covers the surface of the brain and spinal cord. Denticulate ligaments   consist of two lateral flattened bands of pial tissue. adhere to the spinal […]

Lower limb Joints and Ligaments

Hip (coxal) joint Is a multiaxial ball-and-socket synovial joint Is stabilized by the acetabular labrum; the fibrous capsule; and capsular ligaments such as the iliofemoral, ischiofemoral, and pubofemoral ligaments. Has a cavity that is deepened by the fibrocartilaginous acetabular labrum transverse acetabular ligament bridges and converts the acetabular notch into a foramen for passage of […]
