1. Identify the direction that impulses travel through a neuron.

  • A neuron consists of three main regions: the dendrites, a cell body, and an axon.
  • Dendrites receive signals called impulses from other neurons and conduct the impulses to the cell body. Each neuron contains several dendrites. The nucleus of the neuron and many of the cell organelles are found in the cell body. Lastly, an axon carries the nerve impulse from the cell body to other neurons and muscles.

3. Identify the different sensory structures and their corresponding sensory receptors and stimuli

  • Hearing
  • Vibrations called sound waves cause particles in the air to vibrate.
  • Sound waves enter the auditory, or ear, canal and cause a membrane, called the eardrum or tympanum, at the end of the ear canal to vibrate. These vibrations travel through three bones in the middle ear: the malleus (also called the hammer), the incus (anvil), and the stapes (stirrup). As the stapes vibrates, it causes the oval window, a membrane that separates the middle ear from the inner ear, to move back and forth. In the inner ear, a snail-shaped structure called the cochlea is filled with fluid and lined with tiny hair cells. Vibrations cause the fluid inside the cochlea to move like a wave against the hair cells. The hairs cells respond by generating nerve impulses in the auditory nerve and transmitting them to the brain
  • Balance
  • Semicircular canals transmit information about body position and balance to the brain. The three canals are positioned at right angles to one another, and they are fluid-filled and lined with hair cells. When the position of your head changes, fluid within the semicircular canals moves. This causes the hair cells to bend, which in turn sends nerve impulses to the brain.

  • Steroid hormones : Estrogen and testosterone are two examples of steroid hormones.
  • Steroid hormones are soluble in lipids and therefore can diffuse through the plasma membrane of a target cell. Once inside a target cell, they bind to a receptor in the cell. The hormone and the receptor that are bound together bind to DNA in the nucleus, which activates specific gene.

  • Somatic nervous system relay information from external sensory receptors to the central nervous system.
  • Somatic motor nerves really information from central nervous system two skeletal muscle.
  • This is voluntary action.

​

  • Autonomic nervous system carries impulse from central nervous system to the heart and other organs.
  • The body responds involuntarily, not under conscious control.

​

  • Autonomic nervous system has 2 divisions
  • Sympathetic nervous system which controls organs in times of stress.
  • Parasympathetic nervous system which controls organs when the body is at rest.

  • Pancreas

​

  • pancreas secrete hormones insulin and Glucagon; they work together to maintain homeostasis.

​

  • When blood glucose levels are high pancreas release insulin,
  • Insulin helps in conversion of glucose to glycogen which is stored in liver.

​

  • When blood glucose levels are low Glucagon is released,
  • Glucagon binds to liver cell and give signals to convert glycogen to glucose which is released in blood.

​

  • Type 1 Diabetes is a disease when not enough insulin is not produced and the body
  • type 2 diabetes he's caused when the body become insensitive to insulin.

  • Adrenal gland

​

  • Adrenal glands are located above the kidney outer part of kidney is called cortex.
  • Cortex manufacture steroid hormone called aldosterone and a group of hormones called glucocorticoids.
  • Aldosterone affects the kidney and is important for reabsorbing sodium.
  • Cortisol raises blood glucose level and reduce inflammation.

​

  • In a stressful situation the inner portion of adrenal glands secrete epinephrin and norepinephrine.
  • Together these hormones increase heart rate blood pressure breathing rate and sugar levels which are important in increasing the activity of blood cell.
