Answer:
Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. Tight junctions are located within our body's epithelia. Epithelia is the plural of epithelium. Epithelium is a word that refers to the covering of the body's internal and external surfaces. This includes organs (such as skin), blood vessels, and cavities. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Desmosomes are prominently found in cardiac muscle
A typical memory aid that helps in remembering the order in which sound travels from the peripheral to the central components of the auditory pathway would be E.C.O.L.I.M.A.
Sound (high or low-frequency sounds) at first gets to the hair cells of the Ear receptors (E) in Cochlea and cranial nerve number 8 (CN VII), then it gets to the Cochlear nuclei (C) which are cells dedicated to these high or low-frequency sounds.
At the Superior Olivary nucleus (O) sound is localized before it gets to the midbrain - Lateral lemniscus (L) and Inferior colliculus (I). The inferior colliculus receives auditory nerve fibers from ipsilateral superior olivary nuclei through the lateral lemniscus.
Sounds then get to the thalamus at the Medial geniculate body (M) which receives nerve fibers from the inferior colliculus; eventually sounds then get to the auditory cortex.
In summary, ECOLIMA is an easily understandable mnemonic device to help remember how sound waves move from the external ears to the auditory nerves and cortex.
