### animal tissue | nerve tissue:

Fiber bundle
* are nervous tissue
  - part of nervous systems
* come in flexible, goose neck and ring light forms.
* find use primarily in coherent and image transmitting optical systems.
* is nerve tissue

### animal tissue | nerve tissue:

Gray matter
* consists of nerve cell bodies, dendrites, and axons
  - primarily of nerve cells
* contains the neurons while the white matter contains the myelinated nerves
  - parts that have no insulating myelin
* has cell bodies and dendrites involved with reflexes
  - less protein
  - more fluid than white matter, making it easy to distinguish between the two
* is nerve tissue
  - where learning, memory, and reasoning take place
* occupies the butterfly shaped, darker staining region in the center.

Neural tube
* defects exemplify the challenges of congenital anomaly surveillance
  - such as spina bifida and anencephaly
  - with valproate
* develops into the spinal cord and brain in the first four weeks of pregnancy.
* is animal tissue

Neuroglia
* are cells of the nervous system that help protect and support it.
* are the supportive cells of nerve tissue
  - nervetissue
* is animal tissue
  - plant tissue

### animal tissue | pleura:

Pleural effusion
* Most pleural effusions associated with lung cancer are due to tumour.
* are common and are often large enough to be evident radiographically
  - most common with lung or breast cancer and also lymphoma or leukemia
  - often present
  - rare
  - uncommon
* can occur as a complication after heart surgery.
* common and devastating complication in patients with malignant neoplasms
  - problem in cats
* is illnesses
* occurs occasionally.
* prevents the lungs from fully expanding during breathing.
* restricts ventilation and causes progressive shortness of breath.
* tends to be less common but can accompany pneumococcal infection.
* vary in extent.
* very common complication of lung cancer.

Sclera
* are body parts
  - part of eyes
  - solid objects
* have a blue, purple, or gray tint.
  - of variable hue
  - used in reconstructive and glaucoma surgery

### animal tissue | semipermeable body part:

Membrane
* A semipermeable membrane is animal tissue
* Semipermeable membranes make up everything from cell membranes to dialysis bags.

### animal tissue | semipermeable body part | membrane | cell body part:

Membrane
* A cell membrane semipermeable membrane
* All cell membranes contain lipids
  - proteins
* Cell membrane begins to bulge in a process called blebbing
  - contains sterols
  - forms a pouch around the substance
  - has many finger-lide microvilli
* Cell membranes are membranes
  - part of cells
  - come into contact
  - contain water
* Cell membranes enclose cell organelles
* Cell membranes form barriers
  - channels
  - narrow channels
  - play important roles in helping organisms respond to changes in the environment
  - produce and carry the electrical charge by using active transport
  - provide protection
* Every cell membrane has a layer of fat around it.
* Many cell membranes have receptor molecules on their surface.
* Most cell membranes come into contact.
* Most cell membranes contain protein molecules that are embedded in the lipid bilayer
* Most cell membranes enclose cell organelles
  - form narrow channels
* Some cell membranes contain enzymes
  - lead to death
  - maintain conditions
