Human Organisation and Homeostasis Flashcards
Abdominal Cavity
Ventral Cavity in the body containing digestive/Urinary organs
Afferent Pathway
Pathway into the Control Centre
Anatomical Position
Human Position when describing biologically
Anatomy
Makeup of the Human Body
Anterior
Front of body
Control Centre
Part of feedback system that compares stimulus to regular level and sends out a response
Cranial Cavity
Cavity in head the hold brain
Deep
Closer to inside of body
Distal
Further away from connection of limb to body
Dorsal
Back half of body
Effector
Organ that carries out a biological response in a feedback system
Efferent pathway
Pathway out of the Control Centre
Frontal/Coronal Plane
Plane that splits body into front and back sections
Homeostasis
The process that maintains stability and structure of the functions in the body
Inferior
Further down on the body/ towards feet
Lateral
Further away from midline
Medial
Closer to midline
Median/Mid Saggital Plane
Plane that separates body into left and right sections
Mediastinum
The cavity that holds heart
Negative Feedback
A loop system that reduces a stimulus to maintain homeostasis
Organ
Structure made of of two or more different types of tissue
Organ systems
System made of of two or more different organs that has a crucial function within the body
Pelvic Cavity
Cavity in pelvis that hold Urinary/Reproductive organs
Pleural Cavities
Cavities in chest that hold the lungs
Pericardial Cavity
Cavity containing the heart
Physiology
Science of life/ how the body works
Posterior
Back half of the body
Positive Feedback
Feedback loop that enhances the stimulus until it is removed, eg. childbirth
Proximal
Closer to connection of limb to body
Receptor
Thing that senses a change in the regular homeostasis as a result of a stimulus
Superficial
Nearer outside of body, eg skin
Superior
Above/Closer to head
Thoracic Cavity
Cavity in chest that hold the heart and lungs
Tissue
Substance made up of cells in the body
Transverse Plane
Plane that separates the body into superior and inferior sections
Ventral
Front half of body
Vertebral Canal
Dorsal Cavity holding the spinal Cord
