LESSON #2 (6 HOURS)

 

Theme: Structure of ribs and sternum. Thorax as the whole. Formation of the thorax. Structure of clavicle and scapula. Bones of arm, forearm, hand. General data about a skull. Occipital, parietal and frontal bones. Sphenoid and ethmoid bones.

 

Aim: To study the structure of thorax bones, scapula, clavicle. To receive general data about skeleton of upper limb.

To term, find and show in cranium and separate preparations occipital, parietal and frontal bones, their parts, tell about their structure.

 To study location, part, structural features of the sphenoid and ethmoid. Understand their participation in different scull structures.

 

Professional orientation of students: Knowledge the structure of thorax and pectoral girdle bones and humerus is the base to understand location chest viscera and clinic pulmonology, phtysiatry, cardiology and surgical practice.knowledge the structure of occipital, parietal and frontal bones allow to understand morphological peculiarities of cavity for brain and cranial nerves, also important vessels. The correct structure and position of the bones are very important for normal functioning of visual organs, frontal air sinuses, also dural venous sinuses and internal jugular veins. Understanding the structure is a fundamental base for the neurosurgical, and therapeutical practice also traumatology. knowledge the structure of Sphenoid and Ethmoid bones allow to understand morphological peculiarities of cavity for brain and cranial nerves, also important vessels and hypophysis. The correct structure and position of the bones are very important for normal functioning of ethmoid and sphenoid air sinuses, also dural venous sinuses and portion of nasal cavity. Understanding the structure is a fundamental base for the neurosurgical, and therapeutical practice also traumatology and ENT specialiats.

2)    Methodology of Practical Class.

 Work 1.  Studying the anatomy of thorax and shoulder girdle bones.

Independently, attached to active teacher consultation, participating in textbooks and atlases, to learn a rib, sternum, scapula, clavicle on separate preparations and on skeleton.

Work 2. . Studying anatomy of frontal, parietal and occipital bones

After the active teacher’s consultation, using textbooks and atlases, to learn an anatomy of the frontal, parietal and occipital bones on separate preparations and on a skull.

Work 3. Studying anatomy of sphenoid and ethmoid

After the active teacher’s consultation, using textbooks and atlases, to learn anatomy of sphenoid and ethmoid bones on separate preparations and on skull.

 

3)    Demonstrate on preparations:

Ribs: surfaces, margins. Peculiarities of the ribs.

Sternum: parts and structure.

Skeleton and bones of the upper limb.

Clavicle: body, ends, surfaces, formations on the lower surfaces.

Scapula: margins, angles, formations are disposet on costal and dorsal surfaces.

Skull: neurocranium and viscerocranium, border between calvria and base.

Frontal bone: sguama: external, internal, temporal surfaces. Frontal tuber, superciliary arch, supraorbital margin, zygomatic process, frontal crest, groove for the superior sagittal sinus, foramen caecum. Nasal part: nasal spine. Orbital part: ethmoidal notch, trochlear fovea, trochlear spine, fossa for the lacrimal gland.

Parietal bone: external and internal surfaces, frontal, occipital, sagittal and sguamous borders, fronta, occipita, sphenoid and mastoid angles. Groove for the superior sagittal sinus, groove for the sigmoid sinus, superior and inferior temporal lines.

Occipital bone: foramen magnum, sguama, basilar part. Grooves for the transverse and sigmoid sinuses. Hypoglossal and condylar canals. Pharyngeal tubercle.

Sphenoid bone: body, sella turcica, hypophysial fossa, tuberculum sellae, carotid sulcus, sphenoidal crest, sphenoidal conchae, opening of the sphenoid sinus. Small wing: optic canal, supirior orbital fissure. Great wing: cerebral, orbital, temporal and maxillary surfaces: foramen rotundum, foramen ovale and foramen spinosum. Pterygoid processes: medial and lateral plates, pteryoid fossa, pteryoid canal.

Ethmoid bone: cribriform plate, crista galli, perpendicular plate. Ethmoidal labyrinth: ethmoidal cells, orbital plate, superior and middle nasal conchae.
