Students should be able to describe neurons and glia, their morphological components as seen with the light and electron microscope, and some of the fundamental functional roles these cell types play in the nervous system. The concept of a cell started with microscopic observations of dead cork tissue by scientist Robert Hooke in 1665. Mucus, produced by uniglandular cells and glandular tissue, coats the epithelial layer. After fertilization, the zygote gives rise many cells to form the embryo. Chapter 3 cells and tissues answer key strokes. OpenStax Anatomy & Physiology. Epithelial tissues act as coverings, controlling the movement of materials across their surface.

The cell body is the metabolic center of the neuron. 9) or for the person who first described them (e. g., Purkinje cells shown in Figure 8. They are composed of three subunits that are arranged to form a 10-nm diameter tubule. In many cases, this region is the anatomical location for the initiation of the action potential. The skin is an example of a cutaneous membrane. Neurofilaments run in loose bundles around the cell nucleus and other organelles and funnel into the base of the axonal and dendritic processes where they form parallel arrays distributed longitudinally. These different types of synapse are designated by combining the name of the structure of the presynaptic element with that of the postsynaptic structure.

Axolemma is the plasmalemma of the axon. They are the predominant cell type in white matter where they are often located as rows of cells between groups of neuronal processes. Connective tissue binds the various parts of the body together, providing support and protection. Nucleus of the neuron is large and round and is usually centrally located. After studying this chapter, you will be able to: - Describe the structure and function of the cell membrane, including its regulation of materials into and out of the cell. Intercellular adherences have also been observed between fibrous astrocytes.

A connective tissue membrane is built entirely of connective tissue. Postsynaptic density is darkly staining material of postsynaptic cell adjacent to the synapse. The cytoplasm of oligodendrocytes tends to be darker than that of astrocytes with silver stains, and does not contain glial fibrils (although they do contain microtubules). Link to a video that explains how DNA replication ensures that each cell formed during the cell cycle has an exact copy of the DNA. As cell proliferation progresses, three major cell lines are established within the embryo.

Mitochondria are often arranged longitudinally. This virtual slide box contains 275 microscope slides for the learning histology. Axons also contain bundles of microtubules and neurofilaments and scattered mitochondria. The zygote is described as omnipotent because it ultimately gives rise to all the cells in your body including the highly specialized cells of your nervous system. It is important to note that the region of the axon exposed at the node of Ranvier is not bare. Specific types of intercellular junctions have been noted between the processes of protoplasmic astrocytes. 9 Structural Variations.

As will be described later, they also serve as vesicles for reverse transport from axon terminals to the soma. Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue membranes and epithelial membranes (Figure 4. In inhibitory neurons the synaptic vesicle are often flattened as shown in Figure 8. Epithelial membranes are composed of both epithelial tissue and connective tissue. This description is possible because of the development of histochemical and immunocytochemical methods to specifically identify the neurotransmitter type used by neurons. An endoplasmic reticulum is present that regulates Ca2+ level. Many mitochondria are present, especially in the nerve terminal; and. Course Hero member to access this document. Cell body characteristics, including size, shape, location, branching pattern, and density of processes, are also used. View a light-microscopic slide of an axon hillock of a sensory neuron. The nuclear membrane of neurons is like that of other cells - a double membrane punctuated by pores (nuclear pores) which are involved in nuclear-cytoplasmic interactions. Neurofilaments are more abundant than microtubules in axons, whereas microtubules are more abundant than neurofilaments in dendrites. View the shape of a Purkinje cell stained to show its features.

Consequently, the processes of fibrous astrocytes do not form sheets and do not tend to conform to the shape of the surrounding neurons or vascular elements. Cells in the inner layer of the synovial membrane release synovial fluid, a natural lubricant that enables the bones of a joint to move freely against one another with reduced friction. Chapter 17 - The Endocrine System. Epithelial tissue is made of layers of cells that cover the surfaces of the body that come into contact with the exterior world, line internal cavities, and form glands. Oligodendrocytes are also located in both gray and white matter. Organs are assembled from the four basic types of tissues and have cells with specialized functions. Endosome is a membrane-bounded organelle that carries materials ingested by endocytosis and passes them to lysosomes and peroxisomes for degradation. 5 (see enlarged view). Embedded within the neuronal cytoplasm are the organelles common to other cells, the nucleus, nucleolus, endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, lysosomes, endosomes, and peroxisomes.
