Comprehensive Report on the Nervous System, Cranial Nerves, Senses, and Endocrine System

A set of vocabulary flashcards covering key concepts and terminology from the nervous system, cranial nerves, senses, and endocrine system as discussed in the comprehensive report.

Nervous System

A complex network responsible for coordinating voluntary and involuntary actions, and transmitting signals between different body parts.

Central Nervous System (CNS)

Comprises the brain and spinal cord, serving as the primary control center for processing and interpreting sensory information.

Peripheral Nervous System (PNS)

Connects the CNS to limbs and organs, including the somatic nervous system and the autonomic nervous system.

Neurons

Fundamental units of the nervous system that transmit electrical signals and facilitate communication.

Glial Cells

Cells that support and protect neurons and include astrocytes, oligodendrocytes, and microglia.

Cranial Nerves

Twelve pairs of nerves that each have unique functions in the sensory and motor operations of the head and neck.

Olfactory Nerve (I)

Sensory nerve responsible for the sense of smell.

Optic Nerve (II)

Sensory nerve responsible for vision.

Facial Nerve (VII)

Both sensory and motor; responsible for facial expressions, taste, and salivation.

Trigeminal Nerve (V)

Both sensory and motor; involved in facial sensation and motor functions like chewing.

Five Traditional Senses

Sight, hearing, taste, touch, and smell are the primary modalities through which humans interact with their environment.

Sensory Reception

The process by which sensory receptors convert stimuli into neural signals for processing.

Endocrine System

A system consisting of glands that release hormones into the bloodstream to regulate various bodily functions.

Hormones

Chemical messengers produced by glands affecting functions such as metabolism, growth, and mood.

Pituitary Gland

Known as the 'master gland,' it regulates other endocrine glands.

Diabetes Mellitus

An endocrine disorder characterized by insulin imbalance.

Cushing's Syndrome

An endocrine disorder resulting from excessive cortisol.

Homeostasis

The body's ability to maintain stable internal conditions despite changes in external environments.
