Vaginal discharge (also called lochia) that's clear, white or sticky is normal during pregnancy. Swelling may be caused by pregnancy hormones, having more fluid in your body during pregnancy, and pressure from your growing baby on the veins that carry blood to your heart. Dysplasia - abnormality of development; in pathology, alteration in size, shape, and organization of adult cells.

Stuck In Muscle Contractions 7 Little Words Daily Puzzle

The sequence of events that result in the contraction of an individual muscle fiber begins with a signal—the neurotransmitter, ACh—from the motor neuron innervating that fiber. Your body's making pregnancy hormones and you're using a lot of energy, even when you sleep. This condition can happen after the twentieth week of pregnancy. Wear comfortable and supportive shoes.

Nose twitching may be a common side effect of your recent medication or diet. Hematoma - a localized mass of blood, usually clotted, trapped in an organ, space, or tissue, resulting from a break in the wall of a blood vessel.

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. Muscle and nervous tissue will be discussed in detail in future chapters. 5 (see enlarged view). Chapter 10 - Muscle Tissue. Chapter 3 Study Guide. Protoplasmic astrocytes are found primarily in gray matter. After reviewing the Model Neuron above, learn more about the function of each structure by tapping from the list below. Chapter 3 cells and tissues answer key largo. Also, the oligodendrocyte forming a particular myelin internode (i. the myelin between two nodes) is seldom seen directly adjacent to the myelin-wrapped process. Link to website showing tissue sample of multinucleated muscle cells. This description is possible because of the development of histochemical and immunocytochemical methods to specifically identify the neurotransmitter type used by neurons. 9 Structural Variations. The dimers of α and β tubulin subunits polymerize to form proto-filaments arranged in an a helix such that 13 dimer subunits make up each full turn of the a helix. Microglia cells are probably of mesodermal origin.

Chapter 3 Cells And Tissues Answer Key Page 42

The role of oligodendroglia in the central nervous system, particularly of the interfascicular oligodendrocytes, is the formation and maintenance of myelin. Chapter 3 cells and tissues answer key page 42. Link to a slide-show also covering DNA replication. The term tissue is used to describe a group of cells that are similar in structure and perform a specific function. Rough endoplasmic reticulum and ribosomes are present in large but not small dendrites. Consider the difference between a structural cell in the skin and a nerve cell.

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. In a chemical synapse the signal is carried by a diffusable neurotransmitter. 285 electromigration 179 192 456 electron microprobe analysis EMPA 227 EMPA. Beyond the initial segments, the axoplasm lacks rough endoplasmic reticulum and free ribosomes. C. - D. - E. Chapter 3 - The Cellular Level of Organization - Anatomy & Physiology OER - LibGuides at Georgia Highlands College. Which of the following cell types proliferate in the CNS in response to injury? Link to chapter three in the OpenStax Anatomy & Physiology 2e book. Dendrites contain numerous orderly arrays of microtubules and fewer neurofilaments (see below). 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.

Chapter 3 Cells And Tissues Answer Key Strokes

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. The axon in the nodal region usually contains concentrations of organelles, especially mitochondria. Chapter 26 - Fluid, Electrolyte, and Acid-Base Balance. C. Protoplasmic astrocytes. Link to a video where you can learn about ribosomes. The cone-shaped region of the cell body where the axon originates is termed the axon hillock. Keep this theme in mind as you tour the inside of a cell and are introduced to the various types of cells in the body. Muscle tissue allows the body to move and nervous tissues functions in communication. Morphologically the "dendrite" and the "axon" may, therefore, be indistinguishable. Chapter 3 cells and tissues answer key strokes. What happens when a terminally differentiated cell reverts to a less differentiated state? The processes may be large or very fine, sometimes forming sheets that run between axons and dendrites, and may even surround synapses. The synaptic cleft is the gap between the membrane of the pre- and postsynaptic cell.

Multinucleate Muscle Cell. What is the function of synovial membranes? The concept of a cell started with microscopic observations of dead cork tissue by scientist Robert Hooke in 1665. Aggregations of cells in the human body be classified into four types of tissues: epithelial, connective, muscle, and nervous. Neuroglia are divided into two major categories based on size, the macroglia and the microglia. Some cells have a myelinated process that transmits signals toward the cell body. This is because thin cytoplasmic bridges connect the region of the oligodendrocyte cell body to the external wrap of myelin. Epithelial Membranes. Are less electrically excitable than neurons. 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.

Chapter 3 Cells And Tissues Answer Key Largo

These are termed interfascicular oligodendroglia and are involved in the formation and maintenance of the myelin surrounding the neuronal processes nearby. This section will cover the general classifications of the neuroglial cells and describe some of the general properties that distinguish neuroglia from neurons. They are involved in converting proteins to amino acids and glycogen to glucose, the basic nutrient of neurons. This often leads to the formation of glial scar.

Chapter 21 - The Lymphatic and Immune System. Epithelial membranes are composed of both epithelial tissue and connective tissue. Each neuron has only one axon and it is usually straighter and smoother than the dendritic profiles. The axon itself is often surrounded by a membranous material, called the myelin sheath, formed by glia cells. Skip to Main Content. Mitochondria are distributed ubiquitously throughout the cytoplasm of the entire nerve cell and are especially plentiful at presynaptic specializations. Connective tissue, as its name implies, binds the cells and organs of the body together. A connective tissue membrane is built entirely of connective tissue. Furthermore, there are hundreds of different types of neurons based on morphology alone. A nerve cell, on the other hand, may be shaped something like a star, sending out long processes up to a meter in length and may live for the entire lifetime of the organism.

The dendritic processes may branch extensively and are often covered with projections known as dendritic spines. Tissues are classified into four basic types: epithelium, connective tissue (includes cartilage, bone and blood), muscle, and nervous tissue. Synovial membranes are a type of connective tissue membrane that supports mobility in joints. These fine sheet-like processes give the protoplasmic astrocyte cell body a "fuzzy" or murky appearance under the light microscope.

12 Glial Cells and Function. Each germ layer is identified by its relative position: ectoderm (ecto- = "outer"), mesoderm (meso- = "middle"), and endoderm (endo- = "inner"). This region is shown in Figure 8. Link to a website showing tissue sample of a red blood cell extruding its nucleus. Pancreatic Cells' Enzyme Products. 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.
