mammillary bodies

Examples of mammillary bodies in the following topics:

• Limbic System

  • Fornix: A white matter structure that carries signals from the hippocampus to the mammillary bodies and septal nuclei.

• Water Content in the Body

  • In physiology, body water is the water content of the human body.
  • It makes up a significant percentage of total body composition.
  • The water in the body is distributed among various fluid compartments that are interspersed in the various cavities of the body through different tissue types.
  • Body water is regulated largely by the renal and neuro-endocrine systems.
  • There are many clinical methods to determine body water.

• Body Planes and Sections

  • Body planes are hypothetical geometric planes used to divide the body into sections.
  • The sagittal plane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides.
  • It is typically a horizontal plane through the center of the body and is parallel to the ground.
  • Body planes are used to describe anatomical motion in the X-Y-Z coordinate system that the body moves through.
  • Anatomical change during embryological development is also described and measured with body planes.

• Tissues in Levels of Organization

  • The human body is organized at several levels of scale that can each be examined.
  • The human body has many levels of structural organization.
  • Each tissue type has a characteristic role in the body:
  • Each organ is a specialized functional center responsible for a specific function of the body.
  • List the various levels of structural organization that make up the human body

• Thermoregulation

  • If the body must cool down, the body vasodilates these blood vessels. 
  • This allows for our body to release a lot of body heat through radiation. 
  • The body also thermoregulates via the process of sweating (perspiration).
  • In addition, our body thermoregulates using our hair. 
  • Finally, while technically not a thermoregulatory mechanism, the fat associated with our skin does help insulate our body and therefore increases body temperature as a result.

• Body Cavities

  • Vertebrates have fluid-filled spaces called body cavities that contain the organs.
  • By the broadest definition, a body cavity is any fluid-filled space in a multicellular organism.
  • "The human body cavity," normally refers to the ventral body cavity because it is by far the largest one in volume.
  • The dorsal cavity is a continuous cavity located on the dorsal side of the body.
  • This is the most narrow of all body cavities, sometimes described as threadlike.

• Waste Management in Other Body Systems

  • The liver also plays an important function in the management of body waste.
  • It acts as a detoxification system for the body, processing and neutralizing drugs and toxins.
  • While the liver may breakdown or neutralize waste in a different and safer form for the body, it doesn't directly remove the waste from the body.
  • The lungs are responsible for the removal of gaseous waste from the body.
  • The lungs are responsible for the removal of gaseous waste from the body.

• Sweat (Sudoriferous) Glands

  • Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface.
  • Sweat glands, also called sudoriferous glands, are simple tubular glands found almost everywhere on our body. 
  • These are the true sweat glands in the sense of helping to regulate body temperature.  
  • This is because as the water in sweat evaporates, it takes body heat with it.
  • These are also the glands largely responsible for body smells, as their excretions are converted by skin bacteria into various chemicals we associated with body odor. 

• Directional Terms

  • Superior and inferior (cranial and caudal) are used when referring to parts of the body which are toward an end of the body.
  • In general, many structures of the human body are bilateral and symmetrical with the middle of the body, such as the lungs or the arms.
  • Deep refers to structures closer to the interior center of the body.
  • When describing appendages, the proximal end of the appendage connects the appendage to the body, while the distal end is away from the body.
  • Identify the anatomical terms that define the human body in space

• Structural Diversity of Neurons

  • A typical neuron consists of a cell body and neuronal processes such as dendrites and axon.
  • Axons arise from a cone-shaped area of the cell body called axon hillock.
  • Nerve impulses are generated in the axon and transmitted away from the cell body towards the synapse.
  • The cell body is the major biosynthetic center of the neuron.
  • A signal propagating down an axon to the cell body and dendrites of the next cell
