Nervous tissue

Cards (46)

  • What are the key characteristics of muscle tissue?
    • Responsible for movement and contraction
    • Three main types: skeletal, cardiac, and smooth
    • Contains contractile proteins like actin and myosin
  • How do the structures of connective tissue and epithelial tissue differ?
    Connective tissue has cells embedded in an extracellular matrix, while epithelial tissue forms sheets of tightly packed cells
  • What does nervous tissue control and coordinate?
    Bodily functions by processing signals
  • What is the name of the structure labeled as "axon hillock" in the image?
    axon hillock
  • What are the two main functions of nervous tissue?
    Transmit information and control bodily functions
  • What is the function of the axon hillock in a neuron?
    It is the decision-making region
  • How do the structures of neurons contribute to their function?
    Dendrites receive signals, axons transmit them
  • What are the four main types of human tissue?
    Connective, epithelial, muscle, nervous
  • If you wanted to study the detailed structure of a muscle fiber, which type of microscope would you use?
    Electron microscope
  • What is the name of the structure labeled as "nucleus" in the image?
    nucleolus
  • What are the main components of nervous tissue?
    Neurons and glial cells
  • What role do dendrites play in a neuron?
    Dendrites receive signals from other neurons
  • How does nervous tissue transmit information?
    As electrical signals through neurons' axons
  • What is the primary function of connective tissue?
    It supports and binds other tissues
  • What are the key characteristics of nervous tissue?
    • Transmits electrical signals for sensation, movement, and regulation
    • Contains neurons and glial cells
    • Found in the brain, spinal cord, and peripheral nerves
  • What is the role of nervous tissue?
    It controls and communicates information
  • What distinguishes nervous tissue from other tissue types?
    Distinct branches of dendrites and axons
  • What are the parts of a neuron?
    • Cell body
    • Axon hillock (decision-making region)
    • Dendrites (receiving branches)
    • Axon (transmitting branch)
  • How can the information in this image be used to understand the nervous system?
    • Identifies the major nerves and nerve plexuses in the body
    • Shows the organization and distribution of the peripheral nervous system
    • Provides anatomical context for understanding nerve function and pathways
    • Can be used to locate and identify specific nerves for medical procedures or treatments
  • In what way does muscle tissue differ from nervous tissue?
    Muscle tissue enables movement, nervous tissue controls
  • Where is the brain located in the body?
    In the skull
  • What is the name of the nerve located in the lower back?
    Sciatic nerve
  • What are the key characteristics of connective tissue?
    • Provides support and structure
    • Contains cells embedded in an extracellular matrix
    • Examples: bone, cartilage, adipose, blood
  • How does the organization of the peripheral nervous system shown in this image relate to its function?
    • The nerve plexuses allow for the coordination and integration of sensory and motor functions across different body regions
    • The branching pattern of the nerves facilitates the innervation of muscles, skin, and other tissues throughout the body
    • The specific locations of the nerves correspond to the areas of the body they serve, enabling localized control and sensation
  • If a patient had an injury to the sciatic nerve, which part of the body would likely be affected?
    Lower back and leg
  • What is the role of neurons' axons in nervous tissue?
    Enable communication between body parts
  • How does the control function of nervous tissue differ from connective tissue?
    Nervous tissue controls functions, connective tissue supports
  • How are neurons organized in the nervous system?
    Into components creating a communication network
  • What is the name of the structure located at the top of the image?
    Brain
  • What is the name of the structure located below the brain in the image?
    Spinal cord
  • What is the name of the nerve located in the upper arm?
    Radial nerve
  • What runs through the vertebral column?
    Spinal cord
  • What does epithelial tissue do?
    Covers and protects surfaces
  • What branches out from the spinal cord?
    Nerves
  • What do the four basic tissue types build?
    All organs and systems
  • What are plexuses in the nervous system?
    Complex networks formed at multiple points
  • How does muscle tissue function in the body?
    It enables movement
  • What is the function of the axon in a neuron?
    It transmits signals to other neurons
  • What is the name of the nerve located in the lower abdomen?
    Iliohypogastric nerve
  • What are the characteristics of the four primary tissue types?
    • Connective: Supports and binds other tissues
    • Epithelial: Covers and protects surfaces
    • Muscle: Enables movement
    • Nervous: Controls and communicates information
