The Vestibular System01:29

The Vestibular System

39.3K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Neurulation01:30

Neurulation

41.6K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Anatomy of the Brain: Ventricles

2.9K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Somatosensation01:33

Somatosensation

36.3K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Summary
This summary is machine-generated.

Deepwater ghost sharks possess distinct non-visual sensory systems. Harriotta avia uses its rostrum for detailed prey detection, while Hydrolagus bemisi appears to rely less on electroreception.

Area of Science:

  • Marine Biology
  • Sensory Ecology
  • Chondrichthyan Research

Background:

  • Non-visual sensory systems, including mechanosensory (lateral line) and electrosensory systems, are crucial for deepwater chondrichthyans in low-light conditions.
  • These sensory systems are understudied in deepwater chimaeras, a group of cartilaginous fishes.

Purpose of the Study:

  • To describe the peripheral lateral line and electrosensory systems in two chimaera species: Hydrolagus bemisi and Harriotta avia.
  • To compare the morphology and infer the functional importance of these systems in relation to feeding strategies.
  • To provide insights into the sensory modalities of demersal holocephalans vulnerable to anthropogenic disturbances.

Main Methods:

  • Topographic mapping, computed tomography (CT), histology, and scanning electron microscopy were employed.
Sensory organs
  • Detailed analysis of the distribution, abundance, size, and microstructure of lateral line organs (neuromasts) and electrosensory organs (ampullary systems).

    • Main Results:

    • The study mapped the peripheral lateral line and electrosensory organs in H. bemisi and H. avia.
    • Harriotta avia exhibits an elongated rostrum with sense organs, suggesting a role in detailed sensory probing for benthic prey.
    • Hydrolagus bemisi's sensory organ arrangement indicates a potentially lesser reliance on electroreception compared to H. avia.

    Conclusions:

    • The arrangement of sensory organs in these chimaeras suggests adaptations for detecting benthic prey using both mechanosensation and electroreception.
    • Harriotta avia likely uses its rostrum as a specialized sensory probe for hydrodynamic and electric fields.
    • Hydrolagus bemisi may prioritize other sensory inputs over electroreception, highlighting species-specific sensory strategies in deep-sea fishes.
