- Septum pellucidum , a partition between lateral ventricles in the brain
- Connective tissue spaces between the skeletal muscles (intermuscular septa, muscle septum), see fascia
- the rectovaginal septum is a thin partition between the connective tissue sheath (vagina) and the rectum (rectal)
- the vaginal septum is a congenital anatomical malformation of the vagina
- The rectoprostatic fascia or the rectovaginal septum is an accumulation of several layers of connective tissue below the urogenital peritoneum , caudal to the rectovesical excavation in males. It corresponds to the rectovaginal fascia in women
- the transverse septum , as one of the precursors of the diaphragm, is an embryonic structure
- The orbital septum closes the orbit such as a circular membrane around the eyeball running around
- the intersinus, interfrontal septum separates the paired frontal sinus
- the dorsal median septum, middle septum, and dorsal septum are indentations in the spinal cord

In reptiles and amphibians
- in reptiles, septa separate the lungs from the body and the arterial from the venous bloodstream
- in some amphibians, subdivisions of the ventricle in the heart
With birds
- Connective tissue membranes in the air sac ( bird lungs )
In the morphology of invertebrates:
- the partition walls in the gastric space of corals , flower animals and on the corallite of stony corals , with corals a distinction is made between fleshy sarcosis septa (mesentery) and hard sclerosis septa
- the chamber partition in the housing of the cephalopod , here it separates 2 air chambers; Diaphragm, dissepiments.
- a septum inside with armfeet
- in horseshoe worms , the septum separates the metacoel from the mesocoel
- In the case of some snails that shed their shell tips, the resulting opening is closed by a transverse septum
- in the Annelida (annelid worms - earthworms ) septa, which are formed by the mutually adjacent walls of successive Coelom sacs
- in bog animals mostly non-cellular connecting webs between neighboring branches of fenestrate zoaria (colonies of zooids )
- in some graptolites, peridermal strands between adjacent branches of dendroid (branched, ramified) colonies
In botany
- the real partitions coenokarper ovary consisting verwachsenden each carpel areas emerge the individual carpels. False septa, on the other hand (false partitions), arise from growths
- Partition (false or genuine depending on the interpretation) of the replica in pods
In mycology
- the partition between the hyphae compartments, see septum (mycology)
with technical reference:
- Septum (gas chromatography)
- a disruption of the waveguide structure in a polarization switch, see Orthomode Transducer # Septum or Branching
Others:
- Septum piercing , a piercing through the connective tissue below the nasal septum cartilage
