Nervous System

Cards (28)

  • Axons transmit electrical signals away from the cell body to target tissues.
  • The medulla oblongata, located near the base of the brainstem, controls involuntary functions such as breathing, heart rate, blood pressure, swallowing, vomiting, sneezing, coughing, and digestion.
  • The cerebrum, located at the back of the skull, coordinates voluntary movements and maintains posture and balance.
  • Sensory receptors detect changes in the external or internal environment and convert them into neural impulses.
  • Dendrites receive input from other neurons or sensory receptors, transmitting information towards the cell body.
  • Neurons are specialized cells that communicate with other neurons through synapses.
  • Neurons are specialized cells that communicate with one another through electrical and chemical signaling.
  • Nerve fibers are bundles of axons that carry messages between different parts of the nervous system.
  • Nerve fibers consist of bundles of axons surrounded by connective tissue.
  • Axons transmit electrical signals to other neurons or target organs.
  • The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes all nerves outside the CNS.
  • Nerves carry signals between different regions of the body and connect to muscles and glands.
  • Sensory neurons transmit signals to the CNS from sensory organs such as eyes, ears, nose, tongue, skin, muscles, joints, and internal organs.
  • Motor neurons send impulses outward from the CNS to effectors like skeletal muscle, cardiac muscle, smooth muscle, and glands.
  • Dendrites receive incoming information from other neurons.
  • Sensory receptors detect changes in the environment or within the body.
  • The cell body contains the nucleus and organelles necessary for metabolism and protein synthesis.
  • Motor neurons control muscle movement and gland secretion.
  • Synapses are junctions between two nerve cells where communication occurs via neurotransmitters.
  • The PNS is divided into somatic and autonomic divisions based on their functions.
  • Neurons have three basic components: cell body, dendrites, and axon.
  • Neurons are specialized cells that receive, process, and send information throughout the body.
  • Dendrites receive information from other cells and conduct it towards the cell body.
  • Autonomic division regulates involuntary processes such as heart rate, digestion, and breathing.
  • There are three types of neurons: sensory neurons, motor neurons, and interneurons.
  • Neurons are specialized cells that communicate with one another through electrical impulses called action potentials.
  • There are three types of neurons: sensory neurons, motor neurons and association neurons.
  • Myelin sheath surrounds axons and speeds up nerve conduction.
