Q

FUNCTIONS OF CONNECTIVE TISSUE

A
  • establish a structural framework for the body
  • transport fluids and dissolved materials
  • protect delicate organs
  • support surround and interconnect other types of tissue
  • store energy (esp in form triglyceride)
  • defend body from invading micro - organisms

Q

Neuralgia Functions

A
  • Maintain physical structure of nervous tissue
  • Repair nervous tissue frame work after injury

Q

Studying anatomy in NZ

A
  • Bodies form bequests
  • Informed consent from people + families that can be withdrawn
  • Plasternated prosections - process that removes h20 and replaces with silicone - no harm to you - lasts a long time

Q

Human Tissue Act 2008

A
  • Voluntary donations of bodies
  • Requires dual consent by donor + imidiate family member
  • Most held for 18 months, but some kept for longer periods for teaching + research

Q

Sensory and motor pathways

A

Sensory receptors ——-> sensory output over cranial nerves ——-> reflex centres in brain ——-> motor output over cranial nerves ——-> EFFECTORS (muscle, adipose tissue, glands)

Sensory receptors ——-> sensory output of spinal nerves ——-> reflex centres in spinal cord ———> motor output over spinal nerves——-> EFFECTORS (muscles, adipose tissue, glands)

Q

Formation of Tissues

A

Atoms combine to form molecules, which interact to form, cells that secrete and regulate ———> extra cellular material and fluids, combine to form tissues.

24
Q

Functions of neuralgia

A
  • maintain physical structure of nervous tissue

  • Carries information
28
Q

Tissue definition

A

A group of cells or fluid that work together to perform a specific job in the body

29
Q

Positive feedback

A

Homeostatic system where the control variables move further away from the set point. Physiologic positive feedback systems have an end-point
