Endocrine glandular tissue. Structural organization. Outline of the main endocrine glands (pituitary, parathyroid, adrenal, epiphyses, Langerhans islands, interstitial gland of the testis, thyroid).
CONNECTIVE TISSUES Origin and classification of connective tissues. Collagen, reticular and elastic fibers. Fundamental substance: chemical components and functions.
Connective tissue proper. Connective tissue cells: macrophages, mast cells, adipocytes, lymphocytes, granulocytes. Classification of connective tissues proper.
Cartilaginous tissue. Quantity, quality and arrangement of the fibers. Classification. Fundamental substance: chemical components and functions. Cartilage cells.
Bone tissue. General organization. Non-lamellar and lamellar bone tissue. Compact and spongy bone tissue. Structure and ultrastructure of the bone tissue. Bone cells (osteoblasts, osteocytes, osteoclasts). Bone matrix. Direct and indirect ossification.
Blood. Composition. Blood plasma. Erythrocytes. Leukocytes. Platelets. Functions. Myeloid tissue and lymphoid tissue: bone marrow, thymus, spleen, lymph nodes, diffuse lymphoid tissue. Morphology and functions.
CONTRACTILE TISSUES Striated skeletal, cardiac and smooth muscular tissues. Cellular organization and morphological aspects. Myofibrils, myofilaments, sarcomere, sarcoplasmic reticulum. Mechanism of contraction.
NERVOUS TISSUE Generality and subdivisions of the nervous system. General characters and variety of nerve cells. General histology of the nervous system. The neuron. Nerve fiber. Synapses. Structure and ultrastructure. Conduction of the nervous impulse. Function of synapses. Neuroglia: ependymocytes, astrocytes, oligodendrocytes, microglia, Swann cells and satellite cells.
Readings/Bibliography
The choice of the text is free. Any university level book of Histology that include elements of cytology, published in the last decade, is suitable. During the first lessons, the teacher brings to view the most common texts on the market.
Teaching methods
The course will take place in 24 hours of frontal lessons. Specific iconography will be projected to support the theoretical foundations.
Assessment methods
The final test is an oral exam.
The questions will be aimed to ascertain the student knowledge on the topics defined in the course program.
The result achieved in this module will be integrated with the results achieved in the other modules of the integrated course.
Teaching tools
Powerpoint slides of the course are available.
