The axon itself is often surrounded by a membranous material, called the myelin sheath, formed by glia cells. A cutaneous membrane is a multi-layered membrane composed of epithelial and connective tissues. Some cells have a myelinated process that transmits signals toward the cell body. Lysosomes form from the budding off the Golgi apparatus. Neurofilaments are a type of intermediate filament found in nerve cells. Chapter 3 - The Cellular Level of Organization - Anatomy & Physiology OER - LibGuides at Georgia Highlands College. 16, they migrate around the axon, laying a membrane covering around the axon by squeezing out the cytoplasm of the Schwann cell.

Chapter 3 Cells And Tissues Answer Key Of Life
It has been estimated that there are roughly 360 billion glial cells, which comprise 80-90% of the cells in the CNS. A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body (e. g., skin), lines an internal body cavity (e. g., peritoneal cavity), lines a vessel (e. g., blood vessel), or lines a movable joint cavity (e. g., synovial joint). Because these cells start out developmentally as bipolar neurons and then become unipolar as they mature, they are called pseudo-unipolar cells. Tissues are organized into four broad categories based on structural and functional similarities. Chapter 3 cells and tissues answer key strokes. They have a variety of membrane-bound shapes and sizes, ranging in size between 250 and 700 nm in diameter. Nucleolus is in the center of the nuclei of all neurons.
Microfilaments within the axon are usually associated with an area adjacent to the plasmalemma and often are the most dense at the nodes of Ranvier. Specific types of intercellular junctions have been noted between the processes of protoplasmic astrocytes. More recent evidence indicates that the astrocytes can dramatically change size as part of their physiological regulation of the neuronal environment. Chapter 3 cells and tissues answer key of life. The cells composing a tissue share a common embryonic origin. Fibrous astrocytes are found primarily in white matter, have a smoother cell body contour than do protoplasmic astrocytes as seen with glial-specific stains, and have processes that tend to emerge from the cell body radially. An epithelial membrane is composed of an epithelial layer attached to a layer of connective tissue. The MAPS regulate the polymerization of tubulin subunits to form the microtubules. Spines provide a tremendous increase in the surface area available for synaptic contacts.
The reacting microglia have a swollen form with shortened processes and are difficult to discriminate from phagocytes from the periphery or migrating perivascular cells. These categories are epithelial, connective, muscle, and nervous. Cells are also named for their shape (e. g., pyramidal cells shown in Figure 8. A number of conventions have evolved to classify and name neurons. Chapter 3 cells and tissues answer key lime. 2 Client may initially be unaware of the dissociative response Knowl edge of the. Beyond the initial segments, the axoplasm lacks rough endoplasmic reticulum and free ribosomes. It is a prominent, deeply stained spherical inclusion about one-third the size of the nucleus. Although a great deal of variation exists in the size and shape of boutons of individual neurons, synapses can be identified by the presence of the following: Figure 8. Connective tissue binds the various parts of the body together, providing support and protection. About ten years later, Antonie van Leeuwenhoek became the first person to observe living and moving cells under a microscope.

This cell is prominent in the cerebral cortex. Moreover, more than one oligodendrocyte contributes to the myelination of a single internode of an axon. The other type of process in the idealized neuron is the axon. Last Updated: Dec 19, 2022 11:50 AM. Skip to Main Content. Check Admissions Status. 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. Note that epithelial tissue originates in all three layers, whereas nervous tissue derives primarily from the ectoderm and muscle tissue derives from the mesoderm. Nervous tissue is also excitable, allowing for the generation and propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body (Figure 4. Plasmalemma of the neuron appears in the electron microscope as a typical bi-layered cellular membrane, approximately 10 nm thick. 2 shows the types of tissues and organs associated with each of the three germ layers.
Click on a glial cell to move to the related section. List the stages of the cell cycle in order, including the steps of cell division in somatic cells. Link to a slide-show also covering DNA replication. The oligodendrocyte nucleus is smaller than that of the astrocyte, is eccentrically located in the cell body, contains clumps of chromatin and can be stained by alkaline dyes. The interior of the soma consists of cytoplasm, a gel within a microtrabecular lattice formed by the microtubules and associated proteins that make up the cytoskeleton. Membrane Transport Transcript. GHC Notify/Campus Closings. Tags: anatomy, physiology.
The zygote, or fertilized egg, is a single cell formed by the fusion of an egg and sperm cell. Oligodendrocytes are also located in both gray and white matter. Explain the structure and contents of the nucleus, as well as the process of DNA replication. List the morphological and physiological characteristics of some representative cell types in the human body. Chapter 15 - The Autonomic Nervous System. These have been further sub-categorized into Golgi type II cells that are small neurons, usually interneurons, and Golgi type I cells that are large multipolar neurons. Identify the four types of tissue in the body, and describe the major functions of each tissue. Epithelial tissues act as coverings, controlling the movement of materials across their surface. Postsynaptic density is darkly staining material of postsynaptic cell adjacent to the synapse. Alkaline (basic) dyes are used to show nuclear morphology. Link to a video of a tour of a cell. Routinely the fiber or process, which contains the initial segment or trigger zone, is referred to as an axon. The shape and extent of the "dendritic tree" of an individual neuron is indicative of the quantity and variety of information received and processed by that neuron. Myelin is the sleeve of membranous material described by Dr. Byrne, that wraps the neuronal axon as shown in Figure 8.

Ependymal cells line the ventricles of the brain and the central canal of the spinal cord. Additional Resources. Synovial membranes are connective tissue membranes that protect and line the freely-movable joints. Packed tightly into rows and sheets, the squamous skin cells provide a protective barrier for the cells and tissues that lie beneath. A primary responsibility of each cell is to contribute to homeostasis. 1 Introduction to Neurons and Glial Cells. Intercellular adherences have also been observed between fibrous astrocytes. Identify the main tissue types and discuss their roles in the human body. For example, when the transfer of information occurs from an axon to axon or from one terminal to another, the synapse involved is called an axoaxonic synapse.
During injury, the astrocytes proliferate and phagocytize dead cells. Vesicles containing inhibitory neurotransmitter are often flat or elliptical whereas vesicles that contain excitatory neurotransmitter are usually more spherical. Protoplasmic astrocytes are found primarily in gray matter. These probably mediate ion exchange between cells. Describe the functions of the various cytoplasmic organelles. The skin is an example of a cutaneous membrane.
E. Macrophages This answer is INCORRECT. In addition, microtubules are not continuous, and each microtubule is composed of numerous 100 nm units. The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8. Recent studies have indicated that the cleft is not an empty space per se, but is filled with carbohydrate-containing material. Ribosomes are particles composed of ribosomal RNA and ribosomal protein which associate with mRNA and catalyze the synthesis of proteins. Chapter 10 - Muscle Tissue. Which of the following cell types is responsible for the maintenance of pH of the extracellular space of the CNS? It may be the site of branching of the axon, the site of synaptic contacts, or it may be covered with various glial processes.
The nerve ending often has aggregations of dense material in the cytoplasm immediately adjacent to the membrane on the pre- and postsynaptic side of the junction (these are known as presynaptic density or postsynaptic density, respectively. ) Connective tissue, as its name implies, binds the cells and organs of the body together. Synovial membranes are a type of connective tissue membrane that supports mobility in joints. It may appear as densely stained ovoids or as finely dispersed particles or aggregations of granules.
