Coordination and Control

Answer

Coordination is the process by which two or more organs interact and complement each other's functions to maintain homeostasis. For example, during exercise, the heart, lungs, and muscles work togethe…

Answer

The two main systems are the Neural System (Nervous System) and the Endocrine System. The nervous system provides rapid, point-to-point control, while the endocrine system uses hormones for slower, wi…

Answer

Neurons are highly specialized cells of the nervous system that can detect, receive, and transmit electrical and chemical signals. They are the structural and functional units of the neural system.

Answer

A neuron consists of three parts: (1) Cell body (cyton) containing the nucleus, (2) Dendrites – short, branched fibers that receive signals, and (3) Axon – a long fiber that transmits impulses away fr…

Answer

A neuron is a single nerve cell, while a nerve is a bundle of many neuron axons enclosed in connective tissue. Nerves transmit signals between the CNS and body parts.

Answer

The two main parts are: (1) Central Nervous System (CNS) – brain and spinal cord, and (2) Peripheral Nervous System (PNS) – all nerves outside the CNS.

Answer

The CNS is the site of information processing and control. It receives sensory input, interprets it, and sends out motor commands to effectors like muscles and glands.

Answer

Afferent (sensory) fibers carry impulses from sense organs to the CNS. Efferent (motor) fibers carry impulses from the CNS to effectors like muscles and glands.
