  • Ciliary Body
    Ciliary body S.Karmakar HOD Introduction • Ciliary body is the middle part of the uveal tract . It is a ring (slightly eccentric ) shaped structure which projects posteriorly from the scleral spur, with a meridional width varying from 5.5 to 6.5 mm. • It is brown in colour due to melanin pigment. Anteriorly it is confluent with the periphery of the iris (iris root) and anterior part of the ciliary body bounds a part of the anterior chamber angle. Introduction • Posteriorly ciliary body has a crenated or scalloped periphery, known as ora serrata, where it is continuous with the choroid and retina. The ora serrata exhibits forward extensions,known as dentate process, which are well defined on the nasal side and less so temporally. • Ciliary body has a width of approximately 5.9 mm on the nasal side and 6.7 mm on the temporal side. Extension of the ciliary body On the outside of the eyeball, the ciliary body extends from a point about 1.5 mm posterior to the corneal limbus to a point 6.5 to 7.5 mm posterior to this point on the temporal side and 6.5 mm posterior on the nasal side. Parts of ciliary body • Ciliary body, in cross section, is a triangular structure ( in diagram it can be compared as ∆ AOI). Outer side of the triangle (O) is attached with the sclera with suprachoroidal space in between. Anterior side of the triangle (A) forms part of the anterior & posterior chamber. In its middle, the iris is attached. The inner side of the triangle (I) is divided into two parts.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.

  • Elemental Composition of Ora Serrata Pearls—A Form of Focal Nodular
    Letters RESEARCH LETTER Figure 1. Ora Serrata Pearls Elemental Composition of Ora Serrata Pearls— A Two pearls (50 and 10 µm) B Detailed image A Form of Focal Nodular Drusen Examination of the peripheral fundus may reveal discrete pearl- like structures at the furthest extent of the retina. They occur throughout the ora serrata region, but only where a tongue of retina tissue in the form of a dentate process overlies the pars plana. In the later stages, the pigment epithelial covering is lost, exposing the pearl as a glistening bead. To our knowledge, the clinical significance and precise composition of these struc- tures have not been described, although there is suggestion that they consist of drusenlike material. In this study, scan- ning electron microscopy with energy dispersive x-ray spec- troscopy (SEM-EDS) was applied in conjunction with classic histochemical staining techniques to characterize the elemen- tal content of these pearls. Methods | A formalin-fixed enucleated globe was submitted for routine pathological examination and found to contain 3 pearls C Calcified pearl D Pearl without attachment to the at the region of the ora serrata.

It is pierced by spinal nerve roots. The spinal which occur in periostium. canal wall is coverd by periostium, then there is dura mater. The cranial dura mater has several features of importance especially, Between dura mater and periostium there is a , so called especially the dural reflections (derivatives) and the dural venous epidural space, which is filled with adipose tissue and a sinuses(see blood supply) venous plexus , the plexus venosi vertebrales interni Dura mater is attached to avascular arachnoid mater. Between them there is a potential space, so called subdural space which contains a small amount of interstitial fluid. Enables arachnoid mater to slide against dura mater. Dural Reflections The dura separates into two layers at dural reflections (also known as dural folds), places where the inner dural layer is reflected as sheet-like protrusions into the cranial cavity. There are two main dural reflections: • The tentorium cerebelli exists between and separates the cerebellum and • The falx cerebri, which separates the two hemispheres of the brain, is located in the brainstem from the occipital lobes of the cerebrum. The peripheral border of longitudinal cerebral fissure between the hemispheres. Its free edge is close to corpus tentorium is attached to the upper edges of the petrous bones and to the calosum.

  • The Horizontal Raphe of the Human Retina and Its Watershed Zones
    vision Review The Horizontal Raphe of the Human Retina and its Watershed Zones Christian Albrecht May * and Paul Rutkowski Department of Anatomy, Medical Faculty Carl Gustav Carus, TU Dresden, 74, 01307 Dresden, Germany; [email protected] * Correspondence: [email protected] Received: 24 September 2019; Accepted: 6 November 2019; Published: 8 November 2019 Abstract: The horizontal raphe (HR) as a demarcation line dividing the retina and choroid into separate vascular hemispheres is well established, but its development has never been discussed in the context of new findings of the last decades. Although factors for axon guidance are established (e.g., slit-robo pathway, ephrin-protein-receptor pathway) they do not explain HR formation. Early morphological organization, too, fails to establish a HR. The development of the HR is most likely induced by the long posterior ciliary arteries which form a horizontal line prior to retinal organization. The maintenance might then be supported by several biochemical factors. The circulation separate superior and inferior vascular hemispheres communicates across the HR only through their anastomosing capillary beds resulting in watershed zones on either side of the HR. Visual field changes along the HR could clearly be demonstrated in vascular occlusive diseases affecting the optic nerve head, the retina or the choroid. The watershed zone of the HR is ideally protective for central visual acuity in vascular occlusive diseases but can lead to distinct pathological features. Keywords: anatomy; choroid; development; human; retina; vasculature 1. Introduction The horizontal raphe (HR) was first described in the early 1800s as a horizontal demarcation line that extends from the macula to the temporal Ora dividing the temporal retinal nerve fiber layer into a superior and inferior half [1].

Introduction • Sensory information arrives at the CNS • Information is “picked up” by sensory receptors • Sensory receptors are the interface between the nervous system and the internal and external environment • General senses • Refers to temperature, pain, touch, pressure, vibration, and proprioception • Special senses • Refers to smell, taste, balance, hearing, and vision © 2012 Pearson Education, Inc. Receptors • Receptors and Receptive Fields • Free nerve endings are the simplest receptors • These respond to a variety of stimuli • Receptors of the retina (for example) are very specific and only respond to light • Receptive fields • Large receptive fields have receptors spread far apart, which makes it difficult to localize a stimulus • Small receptive fields have receptors close together, which makes it easy to localize a stimulus. © 2012 Pearson Education, Inc.

  • Duplication of Falx Cerebelli, Occipital Sinus, and Internal Occipital Crest
    Romanian Journal of Morphology and Embryology 2009, 50(1):107–110 ORIGINAL PAPER Duplication of falx cerebelli, occipital sinus, and internal occipital crest SUJATHA D’COSTA, A. KRISHNAMURTHY, S. R. NAYAK, SAMPATH MADHYASTA, LATHA V. PRABHU, JIJI P. J, ANU V. RANADE, MANGALA M. PAI, RAJANIGANDHA VADGAONKAR, C. GANESH KUMAR, RAJALAKSHMI RAI Department of Anatomy, Centre for Basic Sciences, Kasturba Medical College, Bejai, Mangalore, Karnataka, India Abstract The incidence of variations of falx cerebelli was studied in 52 adult cadavers of south Indian origin, at Kasturba Medical College Mangalore, after removal of calvaria. In eight (15.4%) cases, we observed duplicated falx cerebelli along with duplicated occipital sinus and internal occipital crest. The length and the distance between each of the falces were measured. The mean length of the right falces cerebelli was 38 mm and the left was 41 mm. The mean distance between these two falces was 20 mm. No marginal sinus was detected. Each of the falces cerebelli had distinct base and apex and possessed a distinct occipital venous sinus on each attached border. These sinuses were noted to drain into the left and right transverse sinus respectively. After detaching the dura mater from inner bony surface of the occipital bone, it was noted that there were two distinct internal occipital crests arising and diverging inferiorly near the posterolateral borders of foramen magnum. The brain from these cadavers appeared grossly normal with no defect of the vermis. Neurosurgeons and neuroradiologists should be aware of such variations, as these could be potential sources of hemorrhage during suboccipital approaches or may lead to erroneous interpretations of imaging of the posterior cranial fossa.
