Anatomy and physiology of ear by maghan das
The document provides information about the anatomy and physiology of the ear. It discusses the three main parts of the ear: external ear, middle ear, and inner ear. The external ear includes the auricle, external auditory canal, and eardrum. The middle ear contains the auditory ossicles (malleus, incus, stapes), which transmit sound vibrations from the eardrum to the inner ear. The inner ear includes the cochlea, which contains hair cells that transduce vibrations into nerve impulses for hearing, and the vestibular system for balance and equilibrium.
Middle Ear Cavity
The middle ear cavity is approximately 15mm vertically and anteroposteriorly. It contains the ear ossicles (malleus, incus, stapes), ligaments, nerves like the chorda tympani and nerve to stapedius, blood vessels, and muscles like the tensor tympani and stapedius. Infections of the middle ear cavity can spread to the cranium, pharynx through the auditory tube, or cause rupture of the tympanic membrane and spread to the mastoid antrum.

Types of Joints
Flaco, a skeleton, introduces himself and wants to give a tour of the different joints in the human body. He explains that without joints, we would not be able to move and would fall over like dominoes. There are three main types of joints - fixed, semi-movable, and movable. Movable joints like hinges, balls and sockets, and gliding joints allow for dancing by enabling movement of the arms, legs, and hips. Flaco concludes by thanking the viewer for learning about joints and invites them to a Day of the Dead dance.

ANATOMY OF NOSE AND PNS.pptx
The nose and paranasal sinuses develop between the 4th and 8th weeks of gestation from five facial swellings. By the 5th week, nasal placodes appear and invaginate to form nasal pits. The medial nasal processes fuse to form the nasal septum. The lateral nasal processes form the lateral nasal walls and turbinates. By the 9th week, the definitive nasal cavity and oral cavity are formed. The paranasal sinuses develop as outpocketings of the lateral nasal walls and include the maxillary, frontal, ethmoid and sphenoid sinuses. Each sinus has distinct anatomical features and relationships. The mucous membrane lining the sinuses and nasal cavity is respiratory type epithelium

Ventricles of brain dr.gosai
The document describes the four ventricles in the brain: the lateral ventricles located in the cerebral hemispheres, the third ventricle between the diencephalon, the cerebral aqueduct connecting the third ventricle to the fourth ventricle, and the fourth ventricle located between the pons and cerebellum. Each ventricle has distinct features such as shape, walls, and structures surrounding them. Blockage of openings between the ventricles can cause hydrocephalus, an abnormal increase in cerebrospinal fluid leading to increased intracranial pressure and potential mental retardation.
Anatomy of Cranial Nerves 5,7,8

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
