Neural Integration 1: Neural Integration in A&P I

Lecture Overview

• Platform: Vimeo
• Institution: Gwinnett Technical College
• Topic: Neural Integration
• Duration: 34 minutes and 4 seconds

Key Concepts Covered

Receptors

• Time: 0:58
• Function as sensory nerve endings
• Detect changes in the environment

Classification of Receptors

• By Location: 3:27

  • Exteroceptors: detect external stimuli
  • Interoceptors: detect internal stimuli
  • Proprioceptors: detect body position

• By Stimulus Type: 5:37

  • Mechanoreceptors: respond to mechanical forces
  • Thermoreceptors: detect temperature changes
  • Photoreceptors: detect light
  • Chemoreceptors: detect chemicals
  • Nociceptors: detect pain

Adaptation and Punctate Distribution

• Time: 12:21
• Adaptation: decrease in receptor sensitivity
• Punctate distribution: uneven distribution of receptors

Proprioceptors

• Time: 16:12
• Provide information about body position
• Located in muscles and joints

Sensory Pathways

• Time: 16:58
• Pathways that carry sensory information to the brain

Referred Pain and Phantom Pain

• Time: 22:38
• Referred Pain: pain perceived in a location other than where the pain stimulus is
• Phantom Pain: sensation of pain in a missing limb

Motor Pathways

• Direct (Pyramidal) Pathway: 25:23

  • Controls voluntary movements

• Indirect (Extrapyramidal) Pathway: 28:40

  • Controls involuntary movements and reflexes
