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. These tiny fluid-filled sacs house components responsible for the thousands of biochemical reactions necessary for an organism to grow and survive. The part of the plasma membrane of the nerve ending that is specialized to form functional contacts with other cells is the synapse. Discuss how a cell differentiates and becomes more specialized. Note that epithelial tissue originates in all three layers, whereas nervous tissue derives primarily from the ectoderm and muscle tissue derives from the mesoderm. Axons also contain bundles of microtubules and neurofilaments and scattered mitochondria. HEALTH SCIENCESPLTW211 - Chapter 2(Azares).docx - CELLS AND TISSUES 3 The basic unit of structure and function in the human body is the cell. Each of a cell’s parts, or | Course Hero. One of the oldest, devised by Golgi in the late 1800's, is based on the complexity of the dendritic tree of the neuron. Epithelial tissue refers to groups of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands. Chapter 3 PowerPoint. You developed from a single fertilized egg cell into the complex organism containing trillions of cells that you see when you look in a mirror.

In Nissl stains, the fibrous astrocytes have a nucleus essentially the same as that of the protoplasmic type with a flecked appearance. Chapter 3 cells and tissues answer key strokes. Epithelial membranes are composed of both epithelial tissue and connective tissue. As in other cells, the principal component of the nucleus is deoxyribonucleic acid (DNA), the substance of the chromosomes and genes. Tissues are classified into four basic types: epithelium, connective tissue (includes cartilage, bone and blood), muscle, and nervous tissue. In gray matter, oligodendroglia are usually located near neurons and, therefore, are known as perineuronal satellite cells.

Connective Tissue Membranes. This type of membrane can be found lining portions of the digestive, respiratory, excretory, and reproductive tracts. Course Hero member to access this document. The cone-shaped region of the cell body where the axon originates is termed the axon hillock. What happens when a terminally differentiated cell reverts to a less differentiated state? Neurons with long axons have a larger cell body and nucleus. As will be described later, they also serve as vesicles for reverse transport from axon terminals to the soma. On the right is the cell soma and dendrites of the Purkinje cell found in the cerebellum and named for the scientist, Purkinje. Each neuron has only one axon and it is usually straighter and smoother than the dendritic profiles. Neurofilaments are a type of intermediate filament found in nerve cells. Chapter 3 cells and tissues answer key page 29. The nucleolus synthesizes ribosomal RNA, which has a major role in protein synthesis. Rough endoplasmic reticulum and ribosomes are present in large but not small dendrites. The chapter three PowerPoint.

Microglia both divide and migrate into regions of cellular injury within the central nervous system in response to injury. Pancreatic Cells' Enzyme Products. Cell body characteristics, including size, shape, location, branching pattern, and density of processes, are also used.

Chapter 3 Cells And Tissues Answer Key Strokes

The membrane of the neuron functions as a receptive surface over its entire extent; however, specific inputs (termed afferents) from other cells are received primarily on the surface of the cell body and on the surface of the specialized processes known as dendrites. The general appearance of microglia is similar to oligodendrocytes, although they are smaller and have undulating processes with spine-like projections. The most numerous cellular constituents of the central nervous system are the non-neuronal, neuroglial ("nerve glue") cells that occupy the space between neurons. 104. blackberry stands that conflict with grazing are not attractive to nesting. Often, neurons that look similar have strikingly different properties. The processes may be large or very fine, sometimes forming sheets that run between axons and dendrites, and may even surround synapses. Bipolar cells are present in the retina and the olfactory bulb. Explain the process by which a cell builds proteins using the DNA code. With silver or glial specific stains, their cell bodies and processes are very irregular. This virtual slide box contains 275 microscope slides for the learning histology. 1 Introduction to Neurons and Glial Cells. C. - D. - E. Which of the following cell types proliferate in the CNS in response to injury?

The membrane lines the joint cavity and contains fibroblasts that produce hyaluronan, which leads to the production of synovial fluid, a natural lubricant that enables the bones of a joint to move freely against one another. For example, they utilize and respond to different neurotransmitter(s). Link to chapter three in the OpenStax Anatomy & Physiology 2e book. The apical surface of this membrane exposed to the external environment and is covered with dead, keratinized cells that help protect the body from desiccation and pathogens.

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. Macrophages appear in the CNS following injury and work together with the CNS glial cells to phagocytize CNS debris. The cleft between the presynaptic cell and the postsynaptic cells is 20 to 40 nm wide and may appear clear or striated. Alkaline (basic) dyes are used to show nuclear morphology. The term tissue is used to describe a group of cells that are similar in structure and perform a specific function. 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. ) Link to a video showing animated mitosis cell division. Link to a video where you can learn about the endomembrane system, which includes the rough and smooth ER and the Golgi body as well as lysosomes and vesicles. Each germ layer is identified by its relative position: ectoderm (ecto- = "outer"), mesoderm (meso- = "middle"), and endoderm (endo- = "inner"). Thus, any disruption in the structure of a tissue can lead to injury or disease. In some regions of the neuron ER is devoid of ribosomes and is termed smooth ER. These differences illustrate one very important theme that is consistent at all organizational levels of biology: the form of a structure is optimally suited to perform particular functions assigned to that structure.
