The document discusses the anatomy and features of canine teeth. It notes that there are four canine teeth, two in the maxilla and two in the mandible. Canines erupt later than other teeth, between ages 9-12. The maxillary canines have a pointed cusp and ridges on the labial surface. They have a prominent cingulum and marginal ridges lingually. The mandibular canines are slightly narrower and have less prominent features lingually. Both have a single long root.

This document provides an overview of the permanent teeth, their eruption timeline, and associated nerves and arteries. It includes:
1) A diagram labeling the different parts of a tooth and surrounding structures like the gum and bone.
2) Tables showing the typical eruption ages for both permanent and deciduous (baby) teeth.
3) Diagrams of the trigeminal nerve branches innervating the teeth and face, as well as the arteries supplying the mouth and salivary glands.

This document provides an overview of tooth morphology basics, including:
- The primary and permanent dentition, with 20 primary teeth and 32 permanent teeth.
- Three main tooth identification systems: the Universal Numbering System, Palmer Notation System, and International Numbering System.
- The four main tissue categories that make up teeth: enamel, dentin, cementum, and pulp.
- Dental terminology used to describe different tooth surfaces and structures.
- The anatomy and morphology of tooth crowns and roots, including features like cusps, ridges, grooves, and root bifurcations.
Enamel is formed through the process of amelogenesis, which involves the life cycle of ameloblasts. Ameloblasts undergo morphological and physiological changes during the secretory, transitional, and maturative stages of amelogenesis. During the secretory stage, ameloblasts develop Tomes' processes which extend into the enamel matrix and help establish the rod and interrod structure of enamel. As enamel matures, ameloblasts transition to having microvilli and modulate between ruffled and smooth shapes to both remove organic material from the enamel and introduce inorganic minerals to fully mineralize the enamel.
Dentin is the tissue that makes up the bulk of the tooth beneath the enamel. It is less mineralized than enamel but more mineralized than bone. Dentin is made up of hydroxyapatite crystals, collagen, and water. It contains microscopic channels called dentinal tubules that originate from the dental pulp and extend outward. With age, secondary dentin deposition and sclerotic dentin formation cause the dentinal tubules to decrease in diameter or become blocked. Dentin provides structural support and shape to the tooth and transmits sensory input from the pulp via the dentinal tubules.
Dentine is the mineralized connective tissue that forms the
bulk of the tooth. It surrounds and protects the dental pulp. In
the crown it is covered by enamel, in the root by cementum.
Unlike enamel, dentine is sensitive and is formed throughout
life, giving rise to secondary dentine. Though the odontoblasts
that form the tissue have processes that lie in tubules within
the dentine, the cell bodies lie at the periphery of the pulp,
constituting a dentine/pulp complex. Being a living tissue,
dentine can react to trauma by forming tertiary dentine.

This document provides information on the structure and organization of the cerebral cortex. It includes descriptions of the different levels and types of cortex (e.g. paleocortex, neocortex, archicortex), cortical layers and cell types, cytoarchitectonic and myeloarchitectonic maps, cortical columns and connections. Diagrams illustrate cortical folding, functional areas, white matter tracts and vascularization.
This document contains diagrams and labels of various structures in the thalamus and surrounding areas in the brain. It identifies nuclei within the thalamus such as the anterior nucleus, dorsomedial nucleus, and pulvinar. It also shows connections between the thalamus and other regions like the cortex, basal ganglia, and brainstem. Pathways such as the optic radiations and peduncles are indicated. The vascular supply to the thalamus from arteries is depicted. In summary, it provides an anatomical overview of the thalamus and its relationships to surrounding brain structures.
The document discusses the electrical conduction system of the heart. It contains diagrams of the aorta, inferior vena cava, and pulmonary veins which are key blood vessels involved in the cardiovascular system. The heart uses an electrical conduction system to coordinate the contraction of the cardiac muscles and maintain an efficient blood flow through this critical circulatory system.

This document contains information about the hypothalamus and its connections. It discusses several nuclei within the hypothalamus, including the paraventricular nucleus, supraoptic nucleus, and suprachiasmatic nucleus. It also mentions the hypothalamic-pituitary system and how neurons in the hypothalamus secrete neurohormones into the portal system to regulate the anterior pituitary gland.
Proiect transfrontalier„Povestea are fir bogat”..AngelaButnaru1
Copiii învață din povești cât de mult contează bunătatea, empatia și prietenia, dându-le ocazia să facă diferența între comportamentele pozitive și cele negative.
Poveștile pentru copii au un rol complex și benefic în dezvoltarea lor, le vor oferi nu doar divertisment, ci și oportunități de învățare și creștere personală.
